Background ========== Qpopper is a widely used server for the POP3 protocol. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-mail/qpopper < 4.0.5-r3 >= 4.0.5-r3 Description =========== Jens Steube discovered that Qpopper doesn't drop privileges to process local files from normal users (CAN-2005-1151). The upstream developers discovered that Qpopper can be forced to create group or world writeable files (CAN-2005-1152). Impact ====== A malicious local attacker could exploit Qpopper to overwrite arbitrary files as root or create new files which are group or world writeable. Workaround ========== There is no known workaround at this time. Resolution ========== All Qpopper users should upgrade to the latest available version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-mail/qpopper-4.0.5-r3" References ========== [ 1 ] CAN-2005-1151 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1151 [ 2 ] CAN-2005-1152 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1152 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200505-17.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.
