The MITRE CVE dictionary describes this issue as:

The reply_sesssetup_and_X_spnego function in sesssetup.c in smbd in Samba before 3.4.8 and 3.5.x before 3.5.2 allows remote attackers to trigger an out-of-bounds read, and cause a denial of service (process crash), via a \\xff\\xff security blob length in a Session Setup AndX request.

Red Hat does not consider this to be a security flaw. This issue can cause smbd per-connection child process crash, resulting in the termination of an attacker's connection. Availability of the smb service is not impacted.
