Background ========== Sylpheed is a lightweight email client and newsreader. Sylpheed-claws is a 'bleeding edge' version of Sylpheed. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 mail-client/sylpheed < 1.0.4 >= 1.0.4 2 mail-client/sylpheed-claws < 1.0.4 >= 1.0.4 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Sylpheed and Sylpheed-claws fail to properly handle messages containing attachments with MIME-encoded filenames. Impact ====== An attacker can send a malicious email message which, when displayed, would cause the program to crash, potentially allowing the execution of arbitrary code with the privileges of the user running the software. 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-1.0.4" All Sylpheed-claws users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=mail-client/sylpheed-claws-1.0.4" References ========== [ 1 ] Sylpheed ChangeLog http://sylpheed.good-day.net/#changes Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200504-02.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.
