Red Hat Security Advisory 2013-0685-01
Posted Mar 26, 2013
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2013-0685-01 - Perl is a high-level programming language commonly used for system administration utilities and web programming. A heap overflow flaw was found in Perl. If a Perl application allowed user input to control the count argument of the string repeat operator, an attacker could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. A denial of service flaw was found in the way Perl's rehashing code implementation, responsible for recalculation of hash keys and redistribution of hash content, handled certain input. If an attacker supplied specially-crafted input to be used as hash keys by a Perl application, it could cause excessive memory consumption.

Authored by Debian | Site debian.org

Debian Linux Security Advisory 2641-1 - Yves Orton discovered a flaw in the rehashing code of Perl. This flaw could be exploited to carry out a denial of service attack against code that uses arbitrary user input as hash keys. Specifically an attacker could create a set of keys of a hash causing a denial of service via memory exhaustion.
