Background ========== The GNU Privacy Guard, GnuPG, is a free replacement for the PGP suite of cryptographic software. The GPGSM utility in GnuPG is responsible for processing X.509 certificates, signatures and encryption as well as S/MIME messages. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-crypt/gnupg < 2.0.16-r1 >= 2.0.16-r1 < 2.0 Description =========== The GPGSM utility in GnuPG contains a use-after-free vulnerability that may be exploited when importing a crafted X.509 certificate explicitly or during the signature verification process. Impact ====== An unauthenticated remote attacker may execute arbitrary code with the privileges of the user running GnuPG by enticing them to import a crafted certificate. Workaround ========== There is no known workaround at this time. Resolution ========== All GnuPG 2.x users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-crypt/gnupg-2.0.16-r1" References ========== [ 1 ] CVE-2010-2547 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-2547 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201110-15.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.
