Multiple vulnerabilities has been found and corrected in perl: 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 via a crafted Unicode string, which triggers a heap-based buffer overflow . Eval injection in the Digest module before 1.17 for Perl allows context-dependent attackers to execute arbitrary commands via the new constructor . The updated packages have been patched to correct these issues.
