Ubuntu Security Notice 1030-1 - It was discovered that Kerberos did not properly determine the acceptability of certain checksums. A remote attacker could use certain checksums to alter the prompt message, modify a response to a Key Distribution Center (KDC) or forge a KRB-SAFE message. It was discovered that Kerberos did not properly determine the acceptability of certain checksums. A remote attacker could use certain checksums to forge GSS tokens or gain privileges. This issue only affected Ubuntu 9.10, 10.04 LTS and 10.10. It was discovered that Kerberos did not reject RC4 key-derivation checksums. An authenticated remote user could use this issue to forge AD-SIGNEDPATH or AD-KDC-ISSUED signatures and possibly gain privileges. This issue only affected Ubuntu 10.04 LTS and 10.10. It was discovered that Kerberos did not properly restrict the use of TGT credentials for armoring TGS requests. A remote authenticated user could use this flaw to impersonate a client. This issue only affected Ubuntu 9.10.

Mandriva Linux Security Advisory 2010-246 - Multiple vulnerabilities were discovered and corrected in krb5. An unauthenticated remote attacker could alter a SAM-2 challenge, affecting the prompt text seen by the user or the kind of response sent to the KDC. An unauthenticated remote attacker has a 1/256 chance of forging KRB-SAFE messages in an application protocol if the targeted pre-existing session uses an RC4 session key. An unauthenticated remote attacker can forge GSS tokens that are intended to be integrity-protected but unencrypted, if the targeted pre-existing application session uses a DES session key. Various other issues have also been addressed. The updated packages have been patched to correct these issues.

Multiple checksum handling vulnerabilities exist in Kerberos. These vulnerabilities are in the MIT implementation of Kerberos (krb5), but because these vulnerabilities arise from flaws in protocol handling logic, other implementations may also be vulnerable.
