c65941da7e6040128ba4788f97396e39Mandriva Linux Security Advisory 2010-130 - Certain invalid GSS-API tokens can cause a GSS-API acceptor (server) to crash due to a null pointer dereference in the GSS-API library. The updated packages have been patched to correct this issue.
47e45bd44a9c5ec752e4b52a2b50ef13Mandriva Linux Security Advisory 2010-129 - The krshd and v4rcp applications in MIT Kerberos 5 (krb5) up to 1.5, and 1.4.x before 1.4.4, when running on Linux and AIX, and Heimdal 0.7.2 and earlier, do not check return codes for setuid calls, which allows local users to gain privileges by causing setuid to fail to drop privileges using attacks such as resource exhaustion. The ftpd and ksu programs in MIT Kerberos 5 (krb5) up to 1.5, and 1.4.x before 1.4.4, and Heimdal 0.7.2 and earlier, do not check return codes for setuid calls, which might allow local users to gain privileges by causing setuid to fail to drop privileges. Certain invalid GSS-API tokens can cause a GSS-API acceptor (server) to crash due to a null pointer dereference in the GSS-API library. The updated packages have been patched to correct these issues.
6c20e9db2952989c815723d2c29fedcfHP Security Bulletin - Potential security vulnerabilities have been identified on HP-UX running Kerberos. These vulnerabilities could be exploited by remote unauthenticated users to create a Denial of Service (DoS) or to execute arbitrary code.
d7ec6c273171108b603677cb0855feb9Debian Linux Security Advisory 2052-1 - Shawn Emery discovered that in MIT Kerberos 5 (krb5), a system for authenticating users and services on a network, a null pointer dereference flaw in the Generic Security Service Application Program Interface (GSS-API) library could allow an authenticated remote attacker to crash any server application using the GSS-API authentication mechanism, by sending a specially-crafted GSS-API token with a missing checksum field.
c00d82b35a17f619a01928d7ec9a8b88Ubuntu 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.
