Updated samba packages that fix a security issue and a bug are now
available for Red Hat Enterprise Linux 2.1, Red Hat Enterprise Linux 3, and
Red Hat Enterprise Linux 4.
This update has been rated as having critical security impact by the Red
Hat Security Response Team.
Samba is a suite of programs used by machines to share files, printers, and other information. A heap-based buffer overflow flaw was found in the way Samba clients handle over-sized packets. If a client connected to a malicious Samba server, it was possible to execute arbitrary code as the Samba client user. It was also possible for a remote user to send a specially crafted print request to a Samba server that could result in the server executing the vulnerable client code, resulting in arbitrary code execution with the permissions of the Samba server. (CVE-2008-1105) Red Hat would like to thank Alin Rad Pop of Secunia Research for responsibly disclosing this issue. Users of Samba are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue.
