Synopsis

The remote Red Hat host is missing a security update for samba3x.

Description

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2011:0306 advisory.

Samba is a suite of programs used by machines to share files, printers, and other information.

A flaw was found in the way Samba handled file descriptors. If an attacker were able to open a large number of file descriptors on the Samba server, they could flip certain stack bits to 1 values, resulting in the Samba server (smbd) crashing. (CVE-2011-0719)

Red Hat would like to thank the Samba team for reporting this issue.

Users of Samba are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue. After installing this update, the smb service will be restarted automatically.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL samba3x package based on the guidance in RHSA-2011:0306.
