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 < 1.0.3 > = 1.0.3 2 mail-client/sylpheed-claws < 1.0.3 > = 1.0.3 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description ========== Sylpheed and Sylpheed-claws fail to properly handle non-ASCII characters in email headers when composing reply messages. Impact ===== An attacker can send an email containing a malicious non-ASCII header which, when replied to, 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 thistime. Resolution ========= All Sylpheed users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =mail-client/sylpheed-1.0.3" All Sylpheed-claws users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =mail-client/sylpheed-claws-1.0.3" References ========= [ 1 ] Sylpheed ChangeLog [ 2 ] CAN-2005-0667 https://www.cve.org/CVERecord?id=CVE-CAN-2005-0667 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200503-26 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.
