In the Linux kernel before 5.2.10, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/hid/usbhid/hiddev.c driver, aka CID-9c09b214f30e.
A Untrusted Search Path vulnerability in openldap2 of openSUSE Factory allows local attackers with control of the ldap user or group to change ownership of arbitrary directory entries to this user/group, leading to escalation to root. This issue affects: openSUSE Factory openldap2 versions prior to 2.6.3-404.1.
When running, the updater service wrote status and log files to an unrestricted location; potentially allowing an unprivileged process to locate and exploit a vulnerability in file handling in the updater service. *Note: This attack requires local system access and only affects Windows. Other operating systems are not affected.*. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71.
A heap-based buffer overflow in the vrend_renderer_transfer_write_iov function in vrend_renderer.c in virglrenderer through 0.8.0 allows guest OS users to cause a denial of service, or QEMU guest-to-host escape and code execution, via VIRGL_CCMD_RESOURCE_INLINE_WRITE commands.
There is heap-based buffer overflow in Linux kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code.
A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host.
yast2-add-on-creator in SUSE inst-source-utils 2008.11.26 before 2008.11.26-0.9.1 and 2012.9.13 before 2012.9.13-0.8.1 allows local users to gain privileges via a crafted (1) file name or (2) directory name.
An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system.
In Ansible, all Ansible Engine versions up to ansible-engine 2.8.5, ansible-engine 2.7.13, ansible-engine 2.6.19, were logging at the DEBUG level which lead to a disclosure of credentials if a plugin used a library that logged credentials at the DEBUG level. This flaw does not affect Ansible modules, as those are executed in a separate process.
Incorrect Default Permissions vulnerability in the openSUSE Tumbleweed hawk2 package allows users with access to the hacluster to escalate to root This issue affects openSUSE Tumbleweed.
qemu-bridge-helper.c in QEMU 3.1 and 4.0.0 does not ensure that a network interface name (obtained from bridge.conf or a --br=bridge option) is limited to the IFNAMSIZ size, which can lead to an ACL bypass.
The Device Mapper multipathing driver (aka multipath-tools or device-mapper-multipath) 0.4.8, as used in SUSE openSUSE, SUSE Linux Enterprise Server (SLES), Fedora, and possibly other operating systems, uses world-writable permissions for the socket file (aka /var/run/multipathd.sock), which allows local users to send arbitrary commands to the multipath daemon.
Google Chrome before 19.0.1084.46 on Windows uses an incorrect search path for the Windows Media Player plug-in, which might allow local users to gain privileges via a Trojan horse plug-in in an unspecified directory.
In Apache HTTP Server 2.4 releases 2.4.17 to 2.4.38, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard. Non-Unix systems are not affected.
Supportutils, before version 3.1-5.7.1, when run with command line argument -A searched the file system for a ndspath binary. If an attacker provides one at an arbitrary location it is executed with root privileges
If supportutils before version 3.1-5.7.1 is run with -v to perform rpm verification and the attacker manages to manipulate the rpm listing (e.g. with CVE-2018-19638) he can execute arbitrary commands as root.

An issue was discovered in the Linux kernel before 4.14.11. A double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c.
The Salsa20 encryption algorithm in the Linux kernel before 4.14.8 does not correctly handle zero-length inputs, allowing a local attacker able to use the AF_ALG-based skcipher interface (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of service (uninitialized-memory free and kernel crash) or have unspecified other impact by executing a crafted sequence of system calls that use the blkcipher_walk API. Both the generic implementation (crypto/salsa20_generic.c) and x86 implementation (arch/x86/crypto/salsa20_glue.c) of Salsa20 were vulnerable.
The HMAC implementation (crypto/hmac.c) in the Linux kernel before 4.14.8 does not validate that the underlying cryptographic hash algorithm is unkeyed, allowing a local attacker able to use the AF_ALG-based hash interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel stack buffer overflow by executing a crafted sequence of system calls that encounter a missing SHA-3 initialization.
A Incorrect Default Permissions vulnerability in the packaging of inn of SUSE Linux Enterprise Server 11-SP3; openSUSE Backports SLE-15-SP2, openSUSE Leap 15.2 allows local attackers to escalate their privileges from the news user to root. This issue affects: SUSE Linux Enterprise Server 11-SP3 inn version inn-2.4.2-170.21.3.1 and prior versions. openSUSE Backports SLE-15-SP2 inn versions prior to 2.6.2. openSUSE Leap 15.2 inn versions prior to 2.6.2.
An issue was discovered in Xen through 4.14.x. There are missing memory barriers when accessing/allocating an event channel. Event channels control structures can be accessed lockless as long as the port is considered to be valid. Such a sequence is missing an appropriate memory barrier (e.g., smp_*mb()) to prevent both the compiler and CPU from re-ordering access. A malicious guest may be able to cause a hypervisor crash resulting in a Denial of Service (DoS). Information leak and privilege escalation cannot be excluded. Systems running all versions of Xen are affected. Whether a system is vulnerable will depend on the CPU and compiler used to build Xen. For all systems, the presence and the scope of the vulnerability depend on the precise re-ordering performed by the compiler used to build Xen. We have not been able to survey compilers; consequently we cannot say which compiler(s) might produce vulnerable code (with which code generation options). GCC documentation clearly suggests that re-ordering is possible. Arm systems will also be vulnerable if the CPU is able to re-order memory access. Please consult your CPU vendor. x86 systems are only vulnerable if a compiler performs re-ordering.
A UNIX Symbolic Link (Symlink) Following vulnerability in python-HyperKitty of openSUSE Leap 15.2, Factory allows local attackers to escalate privileges from the user hyperkitty or hyperkitty-admin to root. This issue affects: openSUSE Leap 15.2 python-HyperKitty version 1.3.2-lp152.2.3.1 and prior versions. openSUSE Factory python-HyperKitty versions prior to 1.3.4-5.1.
Integer overflow in drivers/gpu/drm/i915/i915_gem_execbuffer.c in the i915 driver in the Direct Rendering Manager (DRM) subsystem in the Linux kernel through 3.8.3, as used in Google Chrome OS before 25.0.1364.173 and other products, allows local users to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted application that triggers many relocation copies, and potentially leads to a race condition.
A vulnerability in Google Cloud Platform's guest-oslogin versions between 20190304 and 20200507 allows a user that is only granted the role "roles/compute.osLogin" to escalate privileges to root. Using their membership to the "docker" group, an attacker with this role is able to run docker and mount the host OS. Within docker, it is possible to modify the host OS filesystem and modify /etc/groups to gain administrative privileges. All images created after 2020-May-07 (20200507) are fixed, and if you cannot update, we recommend you edit /etc/group/security.conf and remove the "docker" user from the OS Login entry.

A UNIX Symbolic Link (Symlink) Following vulnerability in chkstat of SUSE Linux Enterprise Server 12, SUSE Linux Enterprise Server 15, SUSE Linux Enterprise Server 11 set permissions intended for specific binaries on other binaries because it erroneously followed symlinks. The symlinks can't be controlled by attackers on default systems, so exploitation is difficult. This issue affects: SUSE Linux Enterprise Server 12 permissions versions prior to 2015.09.28.1626-17.27.1. SUSE Linux Enterprise Server 15 permissions versions prior to 20181116-9.23.1. SUSE Linux Enterprise Server 11 permissions versions prior to 2013.1.7-0.6.12.1.
log.c in Squid Analysis Report Generator (sarg) through 2.3.11 allows local privilege escalation. By default, it uses a fixed temporary directory /tmp/sarg. As the root user, sarg creates this directory or reuses an existing one in an insecure manner. An attacker can pre-create the directory, and place symlinks in it (after winning a /tmp/sarg/denied.int_unsort race condition). The outcome will be corrupted or newly created files in privileged file system locations.
