Problem description

This version fixes several bugs in the Samba suite including two Denial of Service (DoS) Vulnerabilities
Microsoft Windows XP clients with installed Service Pack 2 crash the Samba (smbd) process while printing.
Using macros in the smb.conf 'log file' statement might lead to an infinite recursion.
A wrong counter and pointer handling in samba-vscan sometimes lead to a crashed Samba (smbd) process.
A DoS bug in smbd may allow an unauthenticated user to cause smbd to spawn new processes each one entering an infinite loop. After sending a sufficient amount of packets it is possible to exhaust the memory resources on the server. This issue is known as CAN-2004-0807.
A DoS bug in nmbd may allow an attacker to remotely crash the nmbd daemon. This issue is known as CAN-2004-0808.
