Updated glibc packages fix security vulnerability
Updated glibc packages fix security vulnerability: An off-by-one buffer overflow and underflow in getcwd may lead to memory corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and size passed to getcwd in a setuid program could use this flaw to...
CVE-2021-3999
A flaw was found in glibc. An off-by-one buffer overflow and underflow in getcwd may lead to memory corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and size passed to getcwd in a setuid program could use this flaw to potentially execute...
ROS-20220128-01
The vulnerability in the Polkit library for UNIX-like operating systems is related to improper handling of the number of call parameters in the pkexec setuid binary, which causes the binary to executes environment variables as commands. Exploitation of the vulnerability could allow an attacker to...
A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine.

An integer underflow issue exists in ntfs-3g 2017.3.23. A local attacker could potentially exploit this by running /bin/ntfs-3g with specially crafted arguments from a specially crafted directory to cause a heap buffer overflow resulting in a crash or the ability to execute arbitrary code. In installations where /bin/ntfs-3g is a setuid-root binary this could lead to a local escalation of privileges.
