USN-879-1: Kerberos vulnerability

Releases

• Ubuntu 9.10

Packages

• krb5 -

Details

Jeff Blaine, Radoslav Bodo, Jakob Haufe, and Jorgen Wahlsten discovered
that the Kerberos Key Distribution Center service did not correctly verify
certain network traffic. An unauthenticated remote attacker could send
a specially crafted request that would cause the KDC to crash, leading
to a denial of service.

Update instructions

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

Ubuntu 9.10

• krb5-kdc - 1.7dfsg~beta3-1ubuntu0.1

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