This issue was patched in RHSA-2011:1424.

NVD Description

Note: Versions mentioned in the description apply only to the upstream perl-suidperl package and not the perl-suidperl package as distributed by RHEL. See How to fix? for RHEL:6 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.
