Description

The remote host is missing updates announced in advisory RHSA-2009:1528.

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

A denial of service flaw was found in the Samba smbd daemon. An authenticated, remote user could send a specially-crafted response that would cause an smbd child process to enter an infinite loop. An authenticated, remote user could use this flaw to exhaust system resources by opening multiple CIFS sessions. (CVE-2009-2906)

This update also fixes the following bug:

  • the RHSA-2007:0354 update added code to escape input passed to scripts that are run by Samba. This code was missing c from the list of valid characters, causing it to be escaped. With this update, the previous patch has been updated to include c in the list of valid characters. (BZ#242754)

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