Background ========== MIT Kerberos 5 is a suite of applications that implement the Kerberos network protocol. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-crypt/mit-krb5 < 1.5.2 >= 1.5.2 Description =========== The Kerberos administration daemon, and possibly other applications using the GSS-API or RPC libraries, could potentially call a function pointer in a freed heap buffer, or attempt to free an uninitialized pointer. Impact ====== A remote attacker may be able to crash an affected application, or potentially execute arbitrary code with root privileges. Workaround ========== There is no known workaround at this time. Resolution ========== All MIT Kerberos 5 users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-crypt/mit-krb5-1.5.2" References ========== [ 1 ] CVE-2006-6143 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-6143 [ 2 ] CVE-2006-6144 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-6144 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200701-21.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.
