Description David Walser 2014-11-26 14:42:14 CET

A CVE has been assigned for an issue fixed in libksba 1.3.2:
http://openwall.com/lists/oss-security/2014/11/26/3

Freeze push requested for Cauldron.

Updated package uploaded for Mageia 3 and Mageia 4.

libksba is used through gnupg2, so that's what you need to use to test this.  We have a gnupg test procedure; you just need to use "gpg2" instead of "gpg" as the command to test gnupg2:
https://bugs.mageia.org/show_bug.cgi?id=11306#c3

This probably isn't the most serious issue in the world, but the testing procedure is quick and easy, so if we're able to get it tested today, then great.

Advisory:
========================

Updated libksba packages fix security vulnerability:

By using special crafted S/MIME messages or ECC based OpenPGP data, it is
possible to create a buffer overflow, which could lead to a denial of service
(CVE-2014-9087).
