Debian DLA-871-1 : python3.2 security update

medium Nessus Plugin ID 97966
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.


The remote Debian host is missing a security update.


It was discovered that there was a TLS stripping vulnerability in the smptlib library distributed with the CPython interpreter.

The library did not return an error if StartTLS failed, which might have allowed man-in-the-middle attackers to bypass the TLS protections by leveraging a network position to block the StartTLS command.

For Debian 7 'Wheezy', this issue has been fixed in python3.2 version 3.2.3-7+deb7u1.

We recommend that you upgrade your python3.2 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.


Upgrade the affected packages.
