CVE ID : CVE-2022-30688

Jakub Wilk discovered a local privilege escalation in needrestart, a
utility to check which daemons need to be restarted after library
upgrades. Regular expressions 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.

For the oldstable distribution (buster), this problem has been fixed
in version 3.4-5+deb10u1.

For the stable distribution (bullseye), this problem has been fixed in
version 3.5-4+deb11u1.
