Debian 3.0: DSA 463-1 Moderate: Samba Privilege Escalation Threat

The Debian Security Notice DSA 463-1 addresses a critical flaw in Samba, which allows individuals to escalate their privileges and potentially gain local root access.
Remote user-owned setuid programs can be accessed via "smbmnt" and used to gain local root privileges.

Summary

Samba, a LanManager-like file and printer server for Unix, was found
to contain a vulnerability whereby a local user could use the "smbmnt"
utility, which is setuid root, to mount a file share from a remote
server which contained setuid programs under the control of the user.
These programs could then be executed to gain privileges on the local
system.

For the current stable distribution (woody) this problem has been
fixed in version 2.2.3a-13.

For the unstable distribution (sid) this problem has been fixed in
version 3.0.2-2.

We recommend that you update your samba package.
