CVE-2012-5195 is a vulnerability of currently unknown severity. 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 (memory consumption and crash) or possibly execute arbitrary code via the 'x' string repeat operator.. EPSS estimates a 4.88% chance of exploitation in the next 30 days.
