PwnKit Linux Root Vulnerability Affecting all Distributions
This seems to be a nasty Linux vulnerability. This vulnerability has been in plain sight for 12 years. Lucky for most, there are patches available, so be sure to get ahead of this issue and update those systems.
The Qualys Research Team has discovered a memory corruption vulnerability in polkit’s pkexec, a SUID-root program that is installed by default on every major Linux distribution. This easily exploited vulnerability allows any unprivileged user to gain full root privileges on a vulnerable host by exploiting this vulnerability in its default configuration.
