Security issues should be free and clear after Canonical patched GnuPG vulnerabilities for its Ubuntu 13.04, Ubuntu 12.10, Ubuntu 12.04 LTS, and Ubuntu 10.04 LTS operating systems.
Several security issues ended up fixed in GnuPG, the company said.
One of the fixes was because GnuPG incorrectly handled certain OpenPGP messages. If a user or automated system ended up tricked into processing a specially-crafted message, GnuPG could have consumed resources, resulting in a denial of service.
For a more detailed description of the security problems, you can visit Canonical’s security notification.
Users can fix the security flaws by upgrading the operating systems to the latest gnupg2 and gnupg packages specific to each distribution.
A normal system update, executed with the Update Manager, will implement all the necessary changes. A complete system restart is not necessary to fix all the problems.
