critical Nessus Plugin ID 81463

Language:

Synopsis

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

Description

Samba development team reports :

All versions of Samba from 3.5.0 to 4.2.0rc4 are vulnerable to an unexpected code execution vulnerability in the smbd file server daemon.

A malicious client could send packets that may set up the stack in such a way that the freeing of memory in a subsequent anonymous netlogon packet could allow execution of arbitrary code. This code would execute with root privileges.

Solution

Update the affected packages.
