RHEL 3 : samba (RHSA-2004:259)

Synopsis :

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

Description :

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

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 CVE-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 CVE-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.
