How to fix?

Upgrade Debian:11 zlib to version 1:1.2.8.dfsg-3 or higher.

NVD Description

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

The crc32_big function in crc32.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact via vectors involving big-endian CRC calculation.
