Base vector

Name of the Vulnerable Software and Affected Versions needrestart versions 0.8 through 3.5 before 3.6

Description The issue is related to local privilege escalation. Regexes used to detect Perl, Python, and Ruby interpreters are not anchored, allowing a local user to escalate privileges when needrestart checks if interpreters are using old source files.

Recommendations For versions 0.8 through 3.5 before 3.6, update to version 3.6 or later to resolve the issue. As a temporary workaround, consider restricting the use of the regex detection feature for Perl, Python, and Ruby interpreters until a patch is available.
