RHEL 4 : samba (RHSA-2008:0289)
High Nessus Plugin ID 63855
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated samba packages that fix a security issue are now available for Red Hat Enterprise Linux 4.5 Extended Update Support.
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.
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.
SolutionUpdate the affected packages.
