Debian DSA-4307-1 : python3.5 - security update

critical Nessus Plugin ID 117838
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 a buffer overflow in PyString_DecodeEscape.

Solution

Upgrade the python3.5 packages.

For the stable distribution (stretch), these problems have been fixed in version 3.5.3-1+deb9u1.
