Background ========== fetchmail is a utility that retrieves and forwards mail from remote systems using IMAP, POP, and other protocols. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-mail/fetchmail < 6.2.5.2 >= 6.2.5.2 Description =========== fetchmail does not properly validate UIDs coming from a POP3 mail server. The UID is placed in a fixed length buffer on the stack, which can be overflown. Impact ====== Very long UIDs returned from a malicious or compromised POP3 server can cause fetchmail to crash, resulting in a Denial of Service, or allow arbitrary code to be placed on the stack. Workaround ========== There are no known workarounds at this time. Resolution ========== All fetchmail users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-mail/fetchmail-6.2.5.2" References ========== [ 1 ] Fetchmail Security Advisory http://fetchmail.berlios.de/fetchmail-SA-2005-01.txt [ 2 ] CAN-2005-2335 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2335 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200507-21.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.
