Background ========== uw-imap is the University of Washington's IMAP and POP server daemons. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-mail/uw-imap < 2004g >= 2004g Description =========== Improper bounds checking of user supplied data while parsing IMAP mailbox names can lead to overflowing the stack buffer. Impact ====== Successful exploitation requires an authenticated IMAP user to request a malformed mailbox name. This can lead to execution of arbitrary code with the permissions of the IMAP server. Workaround ========== There are no known workarounds at this time. Resolution ========== All uw-imap users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-mail/uw-imap-2004g" References ========== [ 1 ] CAN-2005-2933 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2933 [ 2 ] iDEFENSE Security Advisory http://www.idefense.com/application/poi/display?id=313&type=vulnerabilities&flashstatus=false Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200510-10.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.
