Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 3.6

Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated samba packages that fix one security issue are now available for Red Hat Enterprise Linux 4, 5, and 6.

The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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.

Solution

Update the affected samba packages.
