RHSA-2004-632: samba

Vulnerability Assessment Summary
Check for the version of the samba packages

Detailed Explanation for this Vulnerability Assessment

Updated samba packages that fix various security vulnerabilities are now
available.

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

During a code audit, Stefan Esser discovered a buffer overflow in Samba
versions prior to 3.0.8 when handling unicode filenames. An authenticated
remote user could exploit this bug which may lead to arbitrary code
execution on the server. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2004-0882 to this issue. Red Hat
believes that the Exec-Shield technology (enabled by default since Update
3) will block attempts to remotely exploit this vulnerability on x86
architectures.

Additionally, a bug was found in the input validation routines in versions
of Samba prior to 3.0.8 that caused the smbd process to consume abnormal
amounts of system memory. An authenticated remote user could exploit this
bug to cause a denial of service. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CVE-2004-0930 to this issue.

Users of Samba should upgrade to these updated packages, which contain
backported security patches, and are not vulnerable to these issues.
