A vulnerability has been found and corrected in perl: Heap-based buffer overflow in the Perl_repeatcpy function in util.c in Perl 5.12.x before 5.12.5, 5.14.x before 5.14.3, and 5.15.x before 15.15.5 allows context-dependent attackers to cause a denial of service or possibly execute arbitrary code via the 'x' string repeat operator . The updated packages have been patched to correct this issue.
