CVE-2012-5195

Name of the Vulnerable Software and Affected Versions Perl versions 5.12.x through 5.12.4 Perl versions 5.14.x through 5.14.2 Perl versions 5.15.x through 5.15.4

Description The issue is related to a heap-based buffer overflow in the Perl repeatcpy function, which can be exploited by context-dependent attackers. This can lead to a denial of service due to memory consumption and crash, or potentially allow the execution of arbitrary code. The exploitation is possible via the 'x' string repeat operator.

Recommendations For Perl versions 5.12.x through 5.12.4, update to version 5.12.5 or later. For Perl versions 5.14.x through 5.14.2, update to version 5.14.3 or later. For Perl versions 5.15.x through 5.15.4, update to version 5.15.5 or later.
