low Nessus Plugin ID 76449

Language:

New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

A denial of service flaw was found in the way the sys_recvfile() function of nmbd, the NetBIOS message block daemon, processed non-blocking sockets. An attacker could send a specially crafted packet that, when processed, would cause nmbd to enter an infinite loop and consume an excessive amount of CPU time. (CVE-2014-0244)

It was discovered that smbd, the Samba file server daemon, did not properly handle certain files that were stored on the disk and used a valid Unicode character in the file name. An attacker able to send an authenticated non-Unicode request that attempted to read such a file could cause smbd to crash. (CVE-2014-3493)

After installing this update, the smb service will be restarted automatically.

Solution

Update the affected packages.
