"The SuSE security audit team, in particular Sebastian Krahmer
<krahmer at suse.de>, has found a flaw in the Samba main smbd code which
could allow an external attacker to remotely and anonymously gain
Super User (root) privileges on a server running a Samba server."
"A buffer overrun condition exists in the SMB/CIFS packet fragment
re-assembly code in smbd which would allow an attacker to cause smbd
to overwrite arbitrary areas of memory in its own process address
space. This could allow a skilled attacker to inject binary specific
exploit code into smbd."

SOLUTION
It is recommended that all Gentoo Linux users who are running
net-fs/samba upgrade to samba-2.2.8 as follows:
emerge sync
emerge samba
emerge clean
