Debian DSA-4306-1 : python2.7 - security update

critical Nessus Plugin ID 117812

Language:

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

Multiple security issues were discovered in Python: ElementTree failed to initialise Expat's hash salt, two denial of service issues were found in difflib and poplib and the shutil module was affected by a command injection vulnerability.

Solution

Upgrade the python2.7 packages.

For the stable distribution (stretch), these problems have been fixed in version 2.7.13-2+deb9u3.
