Scientific Linux Security Update : samba4 on SL6.x i386/x86_64 (20150223)

critical Nessus Plugin ID 81476

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

An uninitialized pointer use flaw was found in the Samba daemon (smbd). A malicious Samba client could send specially crafted netlogon packets that, when processed by smbd, could potentially lead to arbitrary code execution with the privileges of the user running smbd (by default, the root user). (CVE-2015-0240)

After installing this update, the smb service will be restarted automatically.

Solution

Update the affected packages.
