Subject: [USN-41-1] Samba vulnerability

===========================================================
Ubuntu Security Notice USN-41-1		  December 17, 2004
samba vulnerability
CAN-2004-1154
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

samba

The problem can be corrected by upgrading the affected package to
version 3.0.7-1ubuntu6.3. In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

Greg MacManus discovered an integer overflow in Samba's smbd daemon.
Requesting a very large number of access control descriptors from the
server caused an integer overflow, which resulted in a memory
allocation being too short, thus causing a buffer overflow. By sending
carefully crafted data, an attacker could exploit this to execute
arbitrary code on the server with full root permissions.
