Description Sandipan Roy 2022-05-18 07:33:51 UTC 
needrestart 0.8 through 3.5 before 3.6 is prone to local privilege escalation. Regexes to detect the Perl, Python, and Ruby interpreters are not anchored, allowing a local user to escalate privileges when needrestart tries to detect if interpreters are using old source files.
