Severity: Important
Issued on: 2005-01-05
Last updated on: 2005-01-05

CVEs (cve.mitre.org): CVE-2004-1154

Details

Updated samba packages that fix an integer overflow vulnerability are now
available for Red Hat Enterprise Linux 2.1.

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

Greg MacManus of iDEFENSE Labs discovered an integer overflow bug in Samba
versions prior to 3.0.10. An authenticated remote user could exploit this
bug, which could 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.

Please note that the patch included in RHSA-2004:681 was incomplete and may
not have fixed CAN-2004-1154. These packages contain a complete fix for
CAN-2004-1154 along with some additional checks to mitigate similar issues
in the future.

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