Background ========== Heimdal is an implementation of Kerberos 5. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-crypt/heimdal < 0.6.3 >= 0.6.3 Description =========== Przemyslaw Frasunek discovered several flaws in lukemftpd, which also apply to Heimdal ftpd's out-of-band signal handling code. Additionally, a potential vulnerability that could lead to Denial of Service by the Key Distribution Center (KDC) has been fixed in this version. Impact ====== A remote attacker could be able to run arbitrary code with escalated privileges, which can result in a total compromise of the server. Workaround ========== There is no known workaround at this time. Resolution ========== All Heimdal users should upgrade to the latest version: # emerge sync # emerge -pv ">=app-crypt/heimdal-0.6.3" # emerge ">=app-crypt/heimdal-0.6.3" References ========== [ 1 ] Heimdal advisory http://www.pdc.kth.se/heimdal/advisory/2004-09-13/ [ 2 ] Advisory by Przemyslaw Frasunek http://www.frasunek.com/lukemftpd.txt [ 3 ] CAN-2004-0794 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0794 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200409-19.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.
