A local privilege escalation security vulnerability (CVE-2021-3939) could allow attackers to gain root access on Ubuntu systems by exploiting a double-free memory corruption bug in GNOME's AccountsService component.
A recent research paper by a team at University of California, Riverside, shows the existence of previously overlooked side channels in the Linux kernels that can be exploited to attack DNS servers. According to the researchers, the issue with DNS roots in its design, that never really took security as a key concern and that made it extremely hard to retrofit strong security features into it.
CloudLinux’s security platform for Linux-based websites and web servers contains a high-severity PHP deserialization bug, leaving web servers vulnerable to code execution and tekeover.
