| Vector | AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N |
Name of the Vulnerable Software and Affected Versions
python-apt versions 1.9.0ubuntu1 and earlier
Description
The issue is related to the incorrect verification of MD5 hash sums of downloaded files in the
Version.fetch binary() and Version.fetch source() functions of the python-apt module. This could allow a remote attacker to compromise data integrity via a man-in-the-middle attack, potentially leading to the installation of altered packages.Recommendations
For python-apt version 1.9.0ubuntu1 and earlier, update to a fixed version such as 1.9.0ubuntu1.2, 1.6.5ubuntu0.1, 1.1.0~beta1ubuntu0.16.04.7, 0.9.3.5ubuntu3+esm2, or 0.8.3ubuntu7.5 to resolve the issue. As a temporary workaround, consider restricting the use of the
Version.fetch binary() and Version.fetch source() functions until a patch is applied.Fix
Use of a Broken Cryptographic Algorithm
