Debian DSA-821-1 : python2.3 - integer overflow

High Nessus Plugin ID 19790

Synopsis

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

Description

An integer overflow with a subsequent buffer overflow has been detected in PCRE, the Perl Compatible Regular Expressions library, which allows an attacker to execute arbitrary code, and is also present in Python. Exploiting this vulnerability requires an attacker to specify the used regular expression.

Solution

Upgrade the python2.3 packages.

The old stable distribution (woody) does not contain python2.3 packages.

For the stable distribution (sarge) this problem has been fixed in version 2.3.5-3sarge1.
