Debian DLA-1189-1 : python2.7 security update

critical Nessus Plugin ID 104748

Language:

Synopsis

The remote Debian host is missing a security update.

Description

A minor security vulnerability has been discovered in Python 2.7, an interactive high-level object-oriented language.

CVE-2017-1000158

CPython (the reference implementation of Python also commonly known as simply Python) versions 2.6 and 2.7 are vulnerable to an integer overflow and heap corruption, leading to possible arbitrary code execution. The nature of the error has to do with improper handling of large strings with escaped characters.

For Debian 7 'Wheezy', these problems have been fixed in version 2.7.3-6+deb7u4.

We recommend that you upgrade your python2.7 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
