Test ID:1.3.6.1.4.1.25623.1.0.66743
Category:Ubuntu Local Security Checks
Title:Ubuntu USN-881-1 (krb5)
Summary:Ubuntu USN-881-1 (krb5)
Description:The remote host is missing an update to krb5
announced via advisory USN-881-1.

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.

Solution:
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.
