Upgrade Debian:11 perl to version 5.10.1-20 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream perl package and not the perl package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

The (1) lc, (2) lcfirst, (3) uc, and (4) ucfirst functions in Perl 5.10.x, 5.11.x, and 5.12.x through 5.12.3, and 5.13.x through 5.13.11, do not apply the taint attribute to the return value upon processing tainted input, which might allow context-dependent attackers to bypass the taint protection mechanism via a crafted string.
