Red Hat Security Advisory
Synopsis: Updated samba packages fix security issue
Advisory ID: RHSA-2004:498-01
Issue date: 2004-10-04
Updated on: 2004-10-04
Product: Red Hat Enterprise Linux
CVE Names: CAN-2004-0815
- - ---------------------------------------------------------------------
1. Summary:
Updated samba packages that fix an input validation vulnerability are now
available.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386
3. Problem description:
Samba provides file and printer sharing services to SMB/CIFS clients.
Karol Wiesek discovered an input validation issue in Samba prior to 3.0.6.
An authenticated user could send a carefully crafted request to the Samba
server, which would allow access to files outside of the configured file
share. Note: Such files would have to be readable by the account used
for the connection. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0815 to this issue.
This issue does not affect Red Hat Enterprise Linux 3 as a previous erratum
updated to Samba 3.0.6 which is not vulnerable to this issue.
Users of Samba should upgrade to these updated packages, which contain an
upgrade to Samba-2.2.12, which is not vulnerable to this issue.
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

following Web page for the System Administration or Customization
guide specific to your system:
