CVE-2011-2939 Open this link in a new tabHow to fix?
Upgrade Debian:11 perl to version 5.12.4-4 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.
Off-by-one error in the decode_xs function in Unicode/Unicode.xs in the Encode module before 2.44, as used in Perl before 5.15.6, might allow context-dependent attackers to cause a denial of service (memory corruption) via a crafted Unicode string, which triggers a heap-based buffer overflow.
