Background ========== The GNU Privacy Guard, GnuPG, is a free replacement for the PGP suite of cryptographic software. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-crypt/gnupg < 1.4.5 >= 1.4.5 Description =========== Evgeny Legerov discovered a vulnerability in GnuPG that when certain packets are handled an integer overflow may occur. Impact ====== By sending a specially crafted email to a user running an affected version of GnuPG, a remote attacker could possibly execute arbitrary code with the permissions of the user running GnuPG. Workaround ========== There is no known workaround at this time. Resolution ========== All GnuPG users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-crypt/gnupg-1.4.5" References ========== [ 1 ] CVE-2006-3746 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3746 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200608-08.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
