Detail

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS Ubuntu 8.04 LTS Ubuntu 8.10 Ubuntu 9.04 Ubuntu 9.10

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 6.06 LTS:
libkrb53 1.4.3-5ubuntu0.10

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

Ubuntu 8.10:
libkrb53 1.6.dfsg.4~beta1-3ubuntu0.3

Ubuntu 9.04:
libkrb53 1.6.dfsg.4~beta1-5ubuntu2.2

Ubuntu 9.10:
libk5crypto3 1.7dfsg~beta3-1ubuntu0.3

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

Details follow:

It was discovered that Kerberos did not correctly handle invalid AES blocks. An unauthenticated remote attacker could send specially crafted traffic that would crash the KDC service, leading to a denial of service, or possibly execute arbitrary code with root privileges.

Title: Integer Overflow Security Vulnerability in AES and RC4 Decryption in the Solaris Kerberos Crypto Library May Lead to Execution of Arbitrary Code or a Denial of Service (DoS)
Description: Multiple integer underflows in the (1) AES and (2) RC4 decryption functionality in the crypto library in MIT Kerberos 5 (aka krb5) 1.3 through 1.6.3, and 1.7 before 1.7.1, allow remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code by providing ciphertext with a length that is too short to be valid.

Description: It was discovered that krb5, a system for authenticating users and services on a network, is prone to integer underflow in the AES and RC4 decryption operations of the crypto library. A remote attacker can cause crashes, heap corruption, or, under extraordinarily unlikely conditions, arbitrary code execution. For the old stable distribution, this problem has been fixed in version 1.4.4-7etch8. For the stable distribution, this problem has been fixed in version 1.6.dfsg.4~beta1-5lenny2. For the testing distribution, this problem will be fixed soon. For the unstable distribution, this problem has been fixed in version 1.8+dfsg~alpha1-1. We recommend that you upgrade your krb5 package.
