Upgrade Debian:12 pypy3 to version 7.3.11+dfsg-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream pypy3 package and not the pypy3 package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

In Python (aka CPython) up to 3.10.8, the mailcap module does not add escape characters into commands discovered in the system mailcap file. This may allow attackers to inject shell commands into applications that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or arguments). The fix is also back-ported to 3.7, 3.8, 3.9
