CVE-2011-4407

Publication date 26 January 2012

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

ppa.py in Software Properties before 0.81.13.3 does not validate the server certificate when downloading PPA GPG key fingerprints, which allows man-in-the-middle (MITM) attackers to spoof GPG keys for a package repository.
