CVE-2011-0719  (opens in a new tab)
CWE-119  (opens in a new tab)

How to fix?

Upgrade samba to version 3.3.15, 3.4.12, 3.5.7 or higher.

Overview

Affected versions of this package are vulnerable to Out-of-Bounds. Samba 3.x before 3.3.15, 3.4.x before 3.4.12, and 3.5.x before 3.5.7 does not perform range checks for file descriptors before use of the FD_SET macro, which allows remote attackers to cause a denial of service (stack memory corruption, and infinite loop or daemon crash) by opening a large number of files, related to (1) Winbind or (2) smbd.
