Samba ASN.1 Denial of Service

Vulnerability Assessment Summary
checks samba version

Detailed Explanation for this Vulnerability Assessment

The remote Samba server, according to its version number, is vulnerable
to a denial of service.

There is a bug in the remote smbd ASN.1 parsin, which may permit a possible hacker
to cause a denial of service attack against the remote host by sending
a specially crafted ASN.1 packet during the authentication request which
may make the newly-spawned smbd process run into an infinite loop. By
establishing multiple connections and sending such packets, a possible hacker
may consume all the CPU and memory of the remote host, thus crashing it
remotely.

Another bug may permit a possible hacker to crash the remote nmbd process by
sending a malformed NetBIOS packet.


Solution : Upgrade to Samba 3.0.7
Network Security Threat Level: Medium
