Description Josh Bressers 2004-07-20 14:00:30 UTC 
Affected Versions:      Samba 3.0.0 and later

A buffer overrun has been located in the code used to support
the 'mangling method = hash' smb.conf option.  Please be aware
that the default setting for this parameter is 'mangling method
= hash2' and therefore not vulnerable.

Affected Samba 3 installations can avoid this possible security
bug by using the default hash2 mangling method.  Server
installations requiring the hash mangling method are encouraged
to upgrade to Samba 3.0.5.  There are no known exploits for the
bug.
