Buffer overflow in bash 2.0.0, 1.4.17, and other versions allows local attackers to gain privileges by creating an extremely large directory name, which is inserted into the password prompt via the \w option in the PS1 environmental variable when another user changes into that directory.

Buffer overflow in SGI IRIX mailx program.

The alsa-lib package in Red Hat Linux 4 disables stack protection for the libasound.so library, which makes it easier for attackers to execute arbitrary code if there are other vulnerabilities in the library.

Bash treats any character with a value of 255 as a command separator.

setup before version 2.11.4-1.fc28 in Fedora and Red Hat Enterprise Linux added /sbin/nologin and /usr/sbin/nologin to /etc/shells. This violates security assumptions made by pam_shells and some daemons which allow access based on a user's shell being listed in /etc/shells. Under some circumstances, users which had their shell changed to /sbin/nologin could still access the system.

procps-ng before version 3.3.15 is vulnerable to multiple integer overflows leading to a heap corruption in file2strvec function. This allows a privilege escalation for a local attacker who can create entries in procfs by starting processes, which could result in crashes or arbitrary code execution in proc utilities run by other users.

Zsh before version 5.4.2-test-1 is vulnerable to a buffer overflow in the shell autocomplete functionality. A local unprivileged user can create a specially crafted directory path which leads to code execution in the context of the user who tries to use autocomplete to traverse the before mentioned path. If the user affected is privileged, this leads to privilege escalation.

A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause a use-after-free in ext4_xattr_set_entry function and a denial of service or unspecified other impact may occur by renaming a file in a crafted ext4 filesystem image.

The isag utility, which processes sysstat data, allows local users to overwrite arbitrary files via a symlink attack on temporary files, a different vulnerability than CAN-2004-0107.

It was found that the raw midi kernel driver does not protect against concurrent access which leads to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status() which are part of snd_rawmidi_ioctl() handler in rawmidi.c file. A malicious local attacker could possibly use this for privilege escalation.

CloudForms Management Engine (cfme) is vulnerable to an improper security setting in the dRuby component of CloudForms. An attacker with access to an unprivileged local shell could use this flaw to execute commands as a high privileged user.

A flaw was found in Linux kernel's KVM virtualization subsystem. The VMX code does not restore the GDT.LIMIT to the previous host value, but instead sets it to 64KB. With a corrupted GDT limit a host's userspace code has an ability to place malicious entries in the GDT, particularly to the per-cpu variables. An attacker can use this to escalate their privileges.

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.

binutils version 2.32 and earlier contains a Integer Overflow vulnerability in objdump, bfd_get_dynamic_reloc_upper_bound,bfd_canonicalize_dynamic_reloc that can result in Integer overflow trigger heap overflow. Successful exploitation allows execution of arbitrary code.. This attack appear to be exploitable via Local. This vulnerability appears to have been fixed in after commit 3a551c7a1b80fca579461774860574eabfd7f18f.

kernel KVM before versions kernel 4.16, kernel 4.16-rc7, kernel 4.17-rc1, kernel 4.17-rc2 and kernel 4.17-rc3 is vulnerable to a flaw in the way the Linux kernel's KVM hypervisor handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, the processor did not deliver interrupts and exceptions, rather they are delivered once the first instruction after the stack switch is executed. An unprivileged KVM guest user could use this flaw to crash the guest or, potentially, escalate their privileges in the guest.

skk (Simple Kana to Kanji conversion program) 12.1 and earlier, and the ddskk package which is based on skk, creates temporary files insecurely, which allows local users to overwrite arbitrary files.

The RPC code in Linux kernel 2.4 sets the reuse flag when sockets are created, which could allow local users to bind to UDP ports that are used by privileged services such as nfsd.

In glibc 2.26 and earlier there is confusion in the usage of getcwd() by realpath() which can be used to write before the destination buffer leading to a buffer underflow and potential code execution.

tcl/tk package (tcltk) 8.3.1 searches for its libraries in the current working directory before other directories, which could allow local users to execute arbitrary code via a Trojan horse library that is under a user-controlled directory.

Red Hat Linux 7.1 sets insecure permissions on swap files created during installation, which can allow a local attacker to gain additional privileges by reading sensitive information from the swap file, such as passwords.

LPRng in Red Hat Linux 7.0 and 7.1 does not properly drop memberships in supplemental groups when lowering privileges, which could allow a local user to elevate privileges.

Buffer overflow in glob function of glibc allows attackers to cause a denial of service (crash) and possibly execute arbitrary code via a glob pattern that ends in a brace "{" character.

kdesu in kdelibs package creates world readable temporary files containing authentication info, which can allow local users to gain privileges.

Buffer overflow in man program in various distributions of Linux allows local user to execute arbitrary code as group man via a long -S option.

Buffer overflows in the (1) outpack or (2) buf variables of ping in iputils before 20001010, as distributed on Red Hat Linux 6.2 through 7J and other operating systems, may allow local users to gain privileges.

Pluggable Authentication Modules (PAM) in Red Hat Linux 6.1 does not properly lock access to disabled NIS accounts.

screen and rxvt in Red Hat Linux 6.0 do not properly set the modes of tty devices, which allows local users to write to other ttys.

A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap flag(TF) bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exception(#DB) being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate their privileges inside the guest. Linux guests are not affected by this.

virt-bootstrap 1.1.0 allows local users to discover a root password by listing a process, because this password may be present in the --root-password option to virt_bootstrap.py.

Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Client programs). Supported versions that are affected are 5.5.56 and earlier and 5.6.36 and earlier. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where MySQL Server executes to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of MySQL Server accessible data as well as unauthorized read access to a subset of MySQL Server accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of MySQL Server. CVSS 3.0 Base Score 5.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L).

It was found that subscription-manager's DBus interface before 1.19.4 let unprivileged user access the com.redhat.RHSM1.Facts.GetFacts and com.redhat.RHSM1.Config.Set methods. An unprivileged local attacker could use these methods to gain access to private information, or launch a privilege escalation attack.

scoreboard.c in the Apache HTTP Server 2.2.21 and earlier might allow local users to cause a denial of service (daemon crash during shutdown) or possibly have unspecified other impact by modifying a certain type field within a scoreboard shared memory segment, leading to an invalid call to the free function.

The create_script function in the lxc_container module in Ansible before 1.9.6-1 and 2.x before 2.0.2.0 allows local users to write to arbitrary files or gain privileges via a symlink attack on (1) /opt/.lxc-attach-script, (2) the archived container in the archive_path directory, or the (3) lxc-attach-script.log or (4) lxc-attach-script.err files in the temporary directory.

An issue was discovered in Amanda 3.3.1. A user with backup privileges can trivially compromise a client installation. The "runtar" setuid root binary does not check for additional arguments supplied after --create, allowing users to manipulate commands and perform command injection as root.

An issue was discovered in Amanda 3.3.1. A user with backup privileges can trivially compromise a client installation. Amstar is an Amanda Application API script. It should not be run by users directly. It uses star to backup and restore data. It runs binaries with root permissions when parsing the command line argument --star-path.

A flaw was found in Keycloak 12.0.0 where re-authentication does not occur while updating the password. This flaw allows an attacker to take over an account if they can obtain temporary, physical access to a user’s browser. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5
