Debian DSA-1556-2 : perl - heap buffer overflow

medium Nessus Plugin ID 32057

Synopsis

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

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.

Solution

Upgrade the perl packages.

For the stable distribution (etch), this problem has been fixed in version 5.8.8-7etch3.
