RHEL 4 : krb5 (RHSA-2006:0612)

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated krb5 packages are now available for Red Hat Enterprise Linux 4
to correct a privilege escalation security flaw.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

Kerberos is a network authentication system which allows clients and
servers to authenticate to each other through use of symmetric
encryption and a trusted third party, the KDC.

A flaw was found where some bundled Kerberos-aware applications would
fail to check the result of the setuid() call. On Linux 2.6 kernels,
the setuid() call can fail if certain user limits are hit. A local
attacker could manipulate their environment in such a way to get the
applications to continue to run as root, potentially leading to an
escalation of privileges. (CVE-2006-3083).

Users are advised to update to these erratum packages which contain a
backported fix to correct this issue.
