samba security update

Synopsis

samba security update

Type/Severity

Security Advisory: Important

Topic

Updated samba packages that fix an integer overflow vulnerability are now
available for Red Hat Enterprise Linux 3.

Description

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

Greg MacManus of iDEFENSE Labs has discovered an integer overflow bug in
Samba versions prior to 3.0.10. An authenticated remote user could exploit
this bug which may lead to arbitrary code execution on the Samba server.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2004-1154 to this issue.

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