Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

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.

Mitigation

Update the affected package samba.

Vulnerable software versions

Slackware Linux: 8.1 - 13.1
