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

code via the 'x' string repeat operator (CVE-2012-5195).

The updated packages have been patched to correct this issue."
