Red Hat Security Advisory

Synopsis: Updated samba packages fix vulnerabilities
Advisory ID: RHSA-2004:259-01
Issue date: 2004-07-22
Updated on: 2004-07-22
Product: Red Hat Enterprise Linux
Keywords: smb
CVE Names: CAN-2004-0600 CAN-2004-0686
----------------------------------------------------------------------

1. Summary:

Updated samba packages that fix buffer overflows, as well as other various bugs, are now available.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Problem description:

Samba provides file and printer sharing services to SMB/CIFS clients.

Evgeny Demidov discovered a flaw in the internal routine used by the Samba Web Administration Tool (SWAT) in Samba versions 3.0.2 through 3.0.4. When decoding base-64 data during HTTP basic authentication, an invalid base-64 character could cause a buffer overflow. If the SWAT administration service is enabled, this flaw could allow an attacker to execute arbitrary code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0600 to this issue.

Additionally, the Samba team discovered a buffer overflow in the code used to support the 'mangling method = hash' smb.conf option. Please be aware that the default setting for this parameter is 'mangling method = hash2' and therefore not vulnerable. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0686 to this issue.

This release includes the updated upstream version 3.0.4 together with backported security patches to correct these issues as well as a number of post-3.0.4 bug fixes from the Samba subversion repository.

The most important bug fix allows Samba users to change their passwords if Microsoft patch KB 828741 (a critical update) had been applied.

All users of Samba should upgrade to these updated packages, which resolve these issues.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command:

up2date

For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system:
