CVE-2012-5195
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…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.88%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
