NVD Description

Note: Versions mentioned in the description apply only to the upstream perl package and not the perl package as distributed by Echo. See How to fix? for Echo:latest 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.
