Package        : needrestart
Version        : 2.11-3+deb9u2
CVE ID         : CVE-2022-30688
Debian Bug     : 1011154

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 Debian 9 stretch, this problem has been fixed in version
2.11-3+deb9u2.

We recommend that you upgrade your needrestart packages.
