Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The Samba team reports :

Samba is vulnerable to a denial of service, caused by a memory corruption error related to missing range checks on file descriptors being used in the 'FD_SET' macro. By performing a select on a bad file descriptor set, a remote attacker could exploit this vulnerability to cause the application to crash or possibly execute arbitrary code on the system.

Solution

Update the affected packages.
