VMware Workstation Pro 12.x before 12.5.0 and VMware Workstation Player 12.x before 12.5.0 on Windows, when Cortado ThinPrint virtual printing is enabled, allow guest OS users to execute arbitrary code on the host OS or cause a denial of service (host OS memory corruption) via an EMF file.
An out-of-bounds write vulnerability was found in glibc before 2.31 when handling signal trampolines on PowerPC. Specifically, the backtrace function did not properly check the array bounds when storing the frame address, resulting in a denial of service or potential code execution. The highest threat from this vulnerability is to system availability.
VMware Workstation Pro 12.x before 12.5.0 and VMware Workstation Player 12.x before 12.5.0 on Windows, when Cortado ThinPrint virtual printing is enabled, allow guest OS users to execute arbitrary code on the host OS or cause a denial of service (host OS memory corruption) via TrueType fonts embedded in EMFSPOOL.
Race condition in the rds_sendmsg function in net/rds/sendmsg.c in the Linux kernel before 4.3.3 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by using a socket that was not properly bound. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-6937.
It was discovered systemd does not correctly check the content of PIDFile files before using it to kill processes. When a service is run from an unprivileged user (e.g. User field set in the service file), a local attacker who is able to write to the PIDFile of the mentioned service may use this flaw to trick systemd into killing other services and/or privileged processes. Versions before v237 are vulnerable.
A flaw was found in sssd Group Policy Objects implementation. When the GPO is not readable by SSSD due to a too strict permission settings on the server side, SSSD will allow all authenticated users to login instead of denying access.
qmail-verify as used in netqmail 1.06 is prone to an information disclosure vulnerability. A local attacker can test for the existence of files and directories anywhere in the filesystem because qmail-verify runs as root and tests for the existence of files in the attacker's home directory, without dropping its privileges first.
The pkgmgr system service in Tizen allows an unprivileged process to perform package management actions, due to improper D-Bus security policy configurations. Such actions include installing, decrypting, and killing other packages. This affects Tizen before 5.0 M1, and Tizen-based firmwares including Samsung Galaxy Gear series before build RE2.
The Enlightenment system service in Tizen allows an unprivileged process to fully control or capture windows, due to improper D-Bus security policy configurations. This affects Tizen before 5.0 M1, and Tizen-based firmwares including Samsung Galaxy Gear series before build RE2.
The SoundServer/FocusServer system services in Tizen allow an unprivileged process to perform media-related system actions, due to improper D-Bus security policy configurations. Such actions include playing an arbitrary sound file or DTMF tones. This affects Tizen before 5.0 M1, and Tizen-based firmwares including Samsung Galaxy Gear series before build RE2.
The PulseAudio system service in Tizen allows an unprivileged process to control its A2DP MediaEndpoint, due to improper D-Bus security policy configurations. This affects Tizen before 5.0 M1, and Tizen-based firmwares including Samsung Galaxy Gear series before build RE2.
Insufficient web service capability checks made it possible to move categories a user had permission to manage, to a parent category they did not have the capability to manage.
Under certain conditions, a low privileged attacker could load a specially crafted file during installation or upgrade to escalate privileges on Windows and Linux hosts.
arch/x86/kernel/entry_64.S in the Linux kernel before 3.17.5 does not properly handle faults associated with the Stack Segment (SS) segment register, which allows local users to gain privileges by triggering an IRET instruction that leads to access to a GS Base address from the wrong space.
IBM Spectrum Copy Data Management 2.2.0.0 through 2.2.15.0 is vulnerable to reverse tabnabbing where it could allow a page linked to from within IBM Spectrum Copy Data Management to rewrite it. An administrator could enter a link to a malicious URL that another administrator could then click. Once clicked, that malicious URL could then rewrite the original page with a phishing page. IBM X-Force ID: 227363.
A Privilege Context Switching issue was discovered in join.c in Firejail 0.9.68. By crafting a bogus Firejail container that is accepted by the Firejail setuid-root program as a join target, a local attacker can enter an environment in which the Linux user namespace is still the initial user namespace, the NO_NEW_PRIVS prctl is not activated, and the entered mount namespace is under the attacker's control. In this way, the filesystem layout can be adjusted to gain root privileges through execution of available setuid-root binaries such as su or sudo.
Go before 1.17.10 and 1.18.x before 1.18.2 has Incorrect Privilege Assignment. When called with a non-zero flags parameter, the Faccessat function could incorrectly report that a file is accessible.
When generating the systemd service units for the docker snap (and other similar snaps), snapd does not specify Delegate=yes - as a result systemd will move processes from the containers created and managed by these snaps into the cgroup of the main daemon within the snap itself when reloading system units. This may grant additional privileges to a container within the snap that were not originally intended.
An issue was discovered in Xen through 4.14.x. The PCI passthrough code improperly uses register data. Code paths in Xen's MSI handling have been identified that act on unsanitized values read back from device hardware registers. While devices strictly compliant with PCI specifications shouldn't be able to affect these registers, experience shows that it's very common for devices to have out-of-spec "backdoor" operations that can affect the result of these reads. A not fully trusted guest may be able to crash Xen, leading to a Denial of Service (DoS) for the entire system. Privilege escalation and information leaks cannot be excluded. All versions of Xen supporting PCI passthrough are affected. Only x86 systems are vulnerable. Arm systems are not vulnerable. Only guests with passed through PCI devices may be able to leverage the vulnerability. Only systems passing through devices with out-of-spec ("backdoor") functionality can cause issues. Experience shows that such out-of-spec functionality is common; unless you have reason to believe that your device does not have such functionality, it's better to assume that it does.
Improper initialization of default settings in TeamViewer Remote Client prior version 15.51.5 for Windows, Linux and macOS, allow a low privileged user to elevate privileges by changing the personal password setting and establishing a remote connection to a logged-in admin account.
A local privilege escalation vulnerability in Ivanti Secure Access Client for Linux before 22.7R1, allows a low privileged user to execute code as root.
PackageKit's apt backend mistakenly treated all local debs as trusted. The apt security model is based on repository trust and not on the contents of individual files. On sites with configured PolicyKit rules this may allow users to install malicious packages.
An insecure modification vulnerability in the /etc/passwd file was found in the container openshift/jenkins. An attacker with access to the container could use this flaw to modify /etc/passwd and escalate their privileges. This CVE is specific to the openshift/jenkins-slave-base-rhel7-containera as shipped in Openshift 4 and 3.11.
net/netfilter/nf_dup_netdev.c in the Linux kernel 5.4 through 5.6.10 allows local users to gain privileges because of a heap out-of-bounds write. This is related to nf_tables_offload.
An insecure modification vulnerability in the /etc/passwd file was found in the openshift/ocp-release-operator-sdk. An attacker with access to the container could use this flaw to modify /etc/passwd and escalate their privileges. This CVE is specific to the openshift/ansible-operator-container as shipped in Openshift 4.
A privilege escalation flaw was found in the Ansible Automation Platform. This flaw allows a remote authenticated user with 'change user' permissions to modify the account settings of the superuser account and also remove the superuser privileges.
An insecure modification vulnerability in the /etc/passwd file was found in the operator-framework/hadoop as shipped in Red Hat Openshift 4. An attacker with access to the container could use this flaw to modify /etc/passwd and escalate their privileges.
A privilege escalation flaw was found in the node restriction admission plugin of the kubernetes api server of OpenShift. A remote attacker who modifies the node role label could steer workloads from the control plane and etcd nodes onto different worker nodes and gain broader access to the cluster.
The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID.
IBM Db2 for Linux, UNIX and Windows 9.7, 10.1, 10.5, 11.1, and 11.5 is vulnerable to an information disclosure in some scenarios due to unauthorized access caused by improper privilege management when CREATE OR REPLACE command is used. IBM X-Force ID: 225979.
IBM Db2 for Linux, UNIX and Windows 9.7, 10.1, 10.5, 11.1, and 11.5 may be vulnerable to an information disclosure caused by improper privilege management when table function is used. IBM X-Force ID: 221973.
OpenStack Identity (Keystone) before 2013.2.4, 2014.1 before 2014.1.2, and Juno before Juno-2 does not properly handle chained delegation, which allows remote authenticated users to gain privileges by leveraging a (1) trust or (2) OAuth token with impersonation enabled to create a new token with additional roles.
IPython (Interactive Python) is a command shell for interactive computing in multiple programming languages, originally developed for the Python programming language. Affected versions are subject to an arbitrary code execution vulnerability achieved by not properly managing cross user temporary files. This vulnerability allows one user to run code as another on the same machine. All users are advised to upgrade.
The XrayWrapper implementation in Mozilla Firefox before 29.0 and SeaMonkey before 2.26 allows user-assisted remote attackers to bypass intended access restrictions via a crafted web site that is visited in the debugger, leading to unwrapping operations and calls to DOM methods on the unwrapped objects.
accountsservice no longer drops permissions when writting .pam_environment
A privilege escalation flaw was found in Podman. This flaw allows an attacker to publish a malicious image to a public registry. Once this image is downloaded by a potential victim, the vulnerability is triggered after a user runs the 'podman top' command. This action gives the attacker access to the host filesystem, leading to information disclosure or denial of service.
Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 allow remote attackers to bypass the popup blocker via unspecified vectors.
Incomplete fix for CVE-2021-3100. The Apache Log4j hotpatch package starting with log4j-cve-2021-44228-hotpatch-1.1-16 will now explicitly mimic the Linux capabilities and cgroups of the target Java process that the hotpatch is applied to.
The Web Notification API in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 allows remote attackers to bypass intended source-component restrictions and execute arbitrary JavaScript code in a privileged context via a crafted web page for which Notification.permission is granted.
Apport reads and writes information on a crashed process to /proc/pid with elevated privileges. Apport then determines which user the crashed process belongs to by reading /proc/pid through get_pid_info() in data/apport. An unprivileged user could exploit this to read information about a privileged running process by exploiting PID recycling. This information could then be used to obtain ASLR offsets for a process with an existing memory corruption vulnerability. The initial fix introduced regressions in the Python Apport library due to a missing argument in Report.add_proc_environ in apport/report.py. It also caused an autopkgtest failure when reading /proc/pid and with Python 2 compatibility by reading /proc maps. The initial and subsequent regression fixes are in 2.20.11-0ubuntu16, 2.20.11-0ubuntu8.6, 2.20.9-0ubuntu7.12, 2.20.1-0ubuntu2.22 and 2.14.1-0ubuntu3.29+esm3.
In fuse before versions 2.9.8 and 3.x before 3.2.5, fusermount is vulnerable to a restriction bypass when SELinux is active. This allows non-root users to mount a FUSE file system with the 'allow_other' mount option regardless of whether 'user_allow_other' is set in the fuse configuration. An attacker may use this flaw to mount a FUSE file system, accessible by other users, and trick them into accessing files on that file system, possibly causing Denial of Service or other unspecified effects.
Flatpak is a Linux application sandboxing and distribution framework. Prior to versions 1.12.3 and 1.10.6, Flatpak doesn't properly validate that the permissions displayed to the user for an app at install time match the actual permissions granted to the app at runtime, in the case that there's a null byte in the metadata file of an app. Therefore apps can grant themselves permissions without the consent of the user. Flatpak shows permissions to the user during install by reading them from the "xa.metadata" key in the commit metadata. This cannot contain a null terminator, because it is an untrusted GVariant. Flatpak compares these permissions to the *actual* metadata, from the "metadata" file to ensure it wasn't lied to. However, the actual metadata contents are loaded in several places where they are read as simple C-style strings. That means that, if the metadata file includes a null terminator, only the content of the file from *before* the terminator gets compared to xa.metadata. Thus, any permissions that appear in the metadata file after a null terminator are applied at runtime but not shown to the user. So maliciously crafted apps can give themselves hidden permissions. Users who have Flatpaks installed from untrusted sources are at risk in case the Flatpak has a maliciously crafted metadata file, either initially or in an update. This issue is patched in versions 1.12.3 and 1.10.6. As a workaround, users can manually check the permissions of installed apps by checking the metadata file or the xa.metadata key on the commit metadata.
The Crypto API in the Linux kernel before 3.18.5 allows local users to load arbitrary kernel modules via a bind system call for an AF_ALG socket with a module name in the salg_name field, a different vulnerability than CVE-2014-9644.
The ec2tokens API in OpenStack Identity (Keystone) before Havana 2013.2.1 and Icehouse before icehouse-2 does not return a trust-scoped token when one is received, which allows remote trust users to gain privileges by generating EC2 credentials from a trust-scoped token and using them in an ec2tokens API request.
VMware Aria Operations for Logs contains a privilege escalation vulnerability. A malicious actor with non-administrative privileges and network access to Aria Operations for Logs API may be able to perform certain operations in the context of an admin user.
rkt through version 1.30.0 does not isolate processes in containers that are run with `rkt enter`. Processes run with `rkt enter` are given all capabilities during stage 2 (the actual environment in which the applications run). Compromised containers could exploit this flaw to access host resources.
A Improper Privilege Management vulnerability in SUSE Rancher allows write access to the Catalog for any user when restricted-admin role is enabled. This issue affects: SUSE Rancher Rancher versions prior to 2.5.13; Rancher versions prior to 2.6.4.
A flaw was found in the way qemu v1.3.0 and later (virtio-rng) validates addresses when guest accesses the config space of a virtio device. If the virtio device has zero/small sized config space, such as virtio-rng, a privileged guest user could use this flaw to access the matching host's qemu address space and thus increase their privileges on the host.
Linux kernel version after commit bdcf0a423ea1 - 4.15-rc4+, 4.14.8+, 4.9.76+, 4.4.111+ contains a Incorrect Access Control vulnerability in NFS server (nfsd) that can result in remote users reading or writing files they should not be able to via NFS. This attack appear to be exploitable via NFS server must export a filesystem with the "rootsquash" options enabled. This vulnerability appears to have been fixed in after commit 1995266727fa.
A Improper Privilege Management vulnerability in SUSE Rancher allows users with the restricted-admin role to escalate to full admin. This issue affects: SUSE Rancher Rancher versions prior to 2.5.13; Rancher versions prior to 2.6.4.
