Releases

Packages

  • krb5 -

Details

It was discovered that the libraries handling RPCSEC_GSS did not correctly
validate the size of certain packet structures. An unauthenticated remote
user could send a specially crafted request and execute arbitrary code
with root privileges.

Update instructions

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

Ubuntu 7.04
Ubuntu 6.10
Ubuntu 6.06

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