CVE-2021-3156
Sudo, make me a heap overflow! Done, this system is now yours Oh ****... Sudo has a 'make anyone root' bug that needs to be patched – if you're unlucky enough to enable pwfeedback
Security researchers from Qualys have identified a critical heap buffer overflow vulnerability in sudo that can be exploited by rogue users to take over the host system. Sudo is an open-source command-line utility widely used on Linux and other Unix-flavored operating systems. It is designed to give selected, trusted users administrative control when needed. The bug (CVE-2021-3156) found by Qualys, though, allows any local user to gain root-level access on a vulnerable host in its default config...
