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.
