Detail

Synopsis

A double free vulnerability was discovered in Perl, possibly resulting in the execution of arbitrary code and a Denial of Service.

Background

Perl is a stable, cross platform programming language.

Description

Tavis Ormandy and Will Drewry of the Google Security Team have reported a double free vulnerability when processing a crafted regular expression containing UTF-8 characters.

Impact

A remote attacker could possibly exploit this vulnerability to execute arbitrary code or cause a Denial of Service.

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-5.8.8-r5"

All libperl users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-devel/libperl-5.8.8-r2"

Title:	DSA-1556-2 perl - denial of service
Description:	It has been discovered that the Perl interpreter may encounter a buffer overflow condition when compiling certain regular expressions containing Unicode characters. This also happens if the offending characters are contained in a variable reference protected by the \Q...\E quoting construct. When encountering this condition, the Perl interpreter typically crashes, but arbitrary code execution cannot be ruled out.
