Perl: Denial of service

Background

Perl is a highly capable, feature-rich programming language.

Description

S_regmatch() function lacks proper checks before passing arguments to atoi()

Impact

A remote attacker could send a specially crafted input, possibly resulting in a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All Perl users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-lang/perl-5.20.1-r4"
