Background ========== Heimdal is a free implementation of Kerberos 5 that includes a telnet client program. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-crypt/heimdal < 0.6.4 >= 0.6.4 Description =========== Buffer overflow vulnerabilities in the slc_add_reply() and env_opt_add() functions have been discovered by Gael Delalleau in the telnet client in Heimdal. Impact ====== Successful exploitation would require a vulnerable user to connect to an attacker-controlled host using the telnet client, potentially executing arbitrary code with the permissions of the user running the application. Workaround ========== There is no known workaround at this time. Resolution ========== All Heimdal users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-crypt/heimdal-0.6.4" References ========== [ 1 ] CAN-2005-0468 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0468 [ 2 ] CAN-2005-0469 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0469 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200504-28.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.
