Detail

A security issue affects the following Ubuntu releases:

Ubuntu 8.04 LTS Ubuntu 8.10 Ubuntu 9.04

This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the following package versions:

Ubuntu 8.04 LTS:
krb5-kdc 1.6.dfsg.3~beta1-2ubuntu1.4
libkrb53 1.6.dfsg.3~beta1-2ubuntu1.4

Ubuntu 8.10:
krb5-kdc 1.6.dfsg.4~beta1-3ubuntu0.4

Ubuntu 9.04:
krb5-kdc 1.6.dfsg.4~beta1-5ubuntu2.3
libkrb53 1.6.dfsg.4~beta1-5ubuntu2.3

In general, a standard system upgrade is sufficient to effect the necessary changes.

Details follow:

Sol Jerome discovered that the Kerberos kadmind service did not correctly free memory. An unauthenticated remote attacker could send specially crafted traffic to crash the kadmind process, leading to a denial of service. (CVE-2010-0629)

It was discovered that Kerberos did not correctly free memory in the GSSAPI library. If a remote attacker were able to manipulate an application using GSSAPI carefully, the service could crash, leading to a denial of service. (Ubuntu 8.10 was not affected.) (CVE-2007-5901, CVE-2007-5971)

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. (Only Ubuntu 8.04 LTS was affected.) (CVE-2007-5902, CVE-2007-5972)
