Several issues have been found in python-apt, a python interface to libapt-pkg.
It was discovered that python-apt would still use MD5 hashes to validate certain downloaded packages. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could potentially be used to install altered packages.
It was discovered that python-apt could install packages from untrusted repositories, contrary to expectations.
For Debian 8 Jessie
, these problems have been fixed in version
0.9.3.13.
We recommend that you upgrade your python-apt packages.
