Gentoo Linux Security Advisory 201201-13 - Multiple vulnerabilities have been found in MIT Kerberos 5, the most severe of which may allow remote execution of arbitrary code. Versions less than 1.9.2-r1 are affected.
5fe5b981b497ad572aa4e53428ce29f2dcd53be74dc124715f4b3cff09100dd9Ubuntu Security Notice 940-1 - It was discovered that Kerberos did not correctly free memory in the GSSAPI and kdb libraries. If a remote attacker were able to manipulate an application using these libraries carefully, the service could crash, leading to a denial of service. Joel Johnson, Brian Almeida, and Shawn Emery discovered that Kerberos did not correctly verify certain packet structures. An unauthenticated remote attacker could send specially crafted traffic to cause the KDC or kadmind services to crash, leading to a denial of service.

Under some circumstances on some platforms, this could also allow malicious code execution. Successfully inducing code execution by exploiting a double free is believed to be difficult, and no such exploits are known to exist for this vulnerability.
