Background ========== Sylpheed and Claws Mail are two GTK based e-mail clients. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 mail-client/sylpheed < 2.4.5 >= 2.4.5 2 mail-client/claws-mail < 3.0.0 >= 3.0.0 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Ulf Harnhammar from Secunia Research discovered a format string error in the inc_put_error() function in file src/inc.c. Impact ====== A remote attacker could entice a user to connect to a malicious POP server sending specially crafted replies, possibly resulting in the execution of arbitrary code with the privileges of the user running the application. Workaround ========== There is no known workaround at this time. Resolution ========== All Sylpheed users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=mail-client/sylpheed-2.4.5" All Claws Mail users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=mail-client/claws-mail-3.0.0" References ========== [ 1 ] CVE-2007-2958 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2958 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200710-29.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.
