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

high Nessus Plugin ID 19790
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
