Synopsis :

Remote code may be run on the remote server.

Description :

The remote Samba server, according to its version number, is vulnerable to
a remote buffer overrun resulting from an integer overflow vulnerability.

To exploit this flaw, an attacker would need to send to the remote host
a malformed packet containing hundreds of thousands of ACLs, which would
in turn cause an integer overflow resulting in a small pointer being allocated.

An attacker needs a valid account or enough credentials to exploit this
flaw.

Solution :

Upgrade to Samba 3.0.10 or later.

Risk factor :

Critical / CVSS Base Score : 10.0
