Debian DSA-1400-1 : perl - heap overflow

high Nessus Plugin ID 27804

Synopsis

The remote Debian host is missing a security-related update.

Description

Will Drewry and Tavis Ormandy of the Google Security Team have discovered a UTF-8 related heap overflow in Perl's regular expression compiler, probably allowing attackers to execute arbitrary code by compiling specially crafted regular expressions.

Solution

Upgrade the perl package.

For the old stable distribution (sarge), this problem has been fixed in version 5.8.4-8sarge6.

For the stable distribution (etch), this problem has been fixed in version 5.8.8-7etch1.

Some architectures are missing from this DSA; these updates will be released once they are available.
