Synopsis

The remote Debian host is missing a security update.

Description

The urllib library in Python ships support for a second, not well known URL scheme for accessing local files ('local_file://'). This scheme can be used to circumvent protections that try to block local file access and only block the well-known 'file://' schema. This update addresses the vulnerability by disallowing the 'local_file://' URL scheme.

This update also fixes another regresssion introduced in the update issued as DLA-1835-1 that broke installation of libpython3.4-testsuite.

For Debian 8 'Jessie', this problem has been fixed in version 3.4.2-1+deb8u5.

We recommend that you upgrade your python3.4 packages.

For the detailed security status of python3.4 please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/python3.4

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.
