Debian Security Advisory 1387-1 - It has been discovered that the original patch for a buffer overflow in svc_auth_gss.c in the RPCSEC_GSS RPC library in MIT Kerberos 5 (DSA-1368-1) was insufficient to protect from arbitrary code execution in some environments.
50340db3d4f805bcb3c5658fae5d3bac545c80c6847e50ed51e7ec67dc91cd72Gentoo Linux Security Advisory GLSA 200710-01 - A stack based buffer overflow has been discovered in the svcauth_gss_validate() function in file lib/rpc/svc_auth_gss.c when processing an overly long string in a RPC message. Versions less than 0.16 are affected.
5dcb345310412b72c5ee993c17657da7411898965c17fe4fe7957de2cfc7e000Mandriva Linux Security Advisory - A stack buffer overflow vulnerability was discovered in the RPCSEC_GSS RPC library by Tenable Network Security that could potentially allow for the execution of arbitrary code.
fcb6d093bfd1297505d92ab2f4a3e29b414561911105c5fe46ae25a93ef65eafA vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of MIT Kerberos. Authentication is not required to exploit this vulnerability. The specific flaw exists in the svcauth_gss_validate() function. By sending a large authentication context over RPC, a stack based buffer overflow occurs, resulting in a situation allowing for remote code execution.

Another vulnerability (CVE-2007-4000) has been found in kadm5_modify_policy_internal(), which does not check the return values of krb5_db_get_policy() correctly. Versions less than 1.5.3-r1 are affected.
069944d06e3a8b3634e84b6d6ae791d61b76bde151ac2d5c0ca18b8f9799be32Mandriva Linux Security Advisory - A stack buffer overflow vulnerability was discovered in the RPC library used by Kerberos' kadmind program by Tenable Network Security. A remote unauthenticated user who could access kadmind would be able to trigger the flaw and cause it to crash. This issue is only applicable to Kerberos 1.4 and higher. Garrett Wollman found an uninitialized pointer vulnerability in kadmind which a remote unauthenticated attacker able to access kadmind could exploit to cause kadmind to crash. This issue is only applicable to Kerberos 1.5 and higher. The MIT Kerberos Team found a problem with the originally published patch for CVE-2007-3999. A remote unauthenticated attacker able to access kadmind could trigger this flaw and cause kadmind to crash.
419c6d6e4703fc5ed341977474f79acb6d9a9c8398ff622b03be2b6d07615035Ubuntu Security Notice 511-2 - USN-511-1 fixed vulnerabilities in krb5 and librpcsecgss. The fixes were incomplete, and only reduced the scope of the vulnerability, without fully solving it. It was discovered that the libraries handling RPCSEC_GSS did not correctly validate the size of certain packet structures. An unauthenticated remote user could send a specially crafted request and execute arbitrary code with root privileges.
