Red Hat Product Errata RHSA-2004:259 high SHIPPED_LIVE Important: samba security update 2004-07-22 04:00:00 UTC

Description Mark J. Cox 2004-07-15 07:50:00 UTC
** This issue is currently embargoed **

The Samba team reported to us on July 14th that the internal routine
used by the Samba Web Administration Tool (SWAT) to decode the base64
data during HTTP basic authentication is subject to a buffer overrun
caused by an invalid base64 character.

Affected Samba installations include those running v3.0.2 or later and
meeting one of the following three requirements:

(a) Servers using the ldapsam passdb backend
(b) Servers running winbindd and allowing 3rd party applications to
issue authentication requests via the ntlm_auth tool included with Samba.
(c) Servers running SWAT.

RHSA-2004:064 upgraded RHEL3 users to a vulnerable version of Samba,
therefore RHEL3 is affected by this issue.

The embargo is set at July 20th, at 6am GMT-6 at which time Samba
3.0.5 will be released.

This issue does not affect RHEL2.1 which is on Samba version 2.2.7.
