Test ID:1.3.6.1.4.1.25623.1.0.69352
Category:Ubuntu Local Security Checks
Title:Ubuntu USN-1088-1 (krb5)
Summary:Ubuntu USN-1088-1 (krb5)
Description:The remote host is missing an update to krb5
announced via advisory USN-1088-1.

Details follow:

Cameron Meadors discovered that the MIT Kerberos 5 Key Distribution
Center (KDC) daemon is vulnerable to a double-free condition if
the Public Key Cryptography for Initial Authentication (PKINIT)
capability is enabled. This could allow a remote attacker to cause
a denial of service.

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

Ubuntu 9.10:
krb5-kdc 1.7dfsg~
beta3-1ubuntu0.12

Ubuntu 10.04 LTS:
krb5-kdc 1.8.1+dfsg-2ubuntu0.8

Ubuntu 10.10:
krb5-kdc 1.8.1+dfsg-5ubuntu0.6

In general, a standard system update will make all the necessary changes.
