samba - missing permission checks

Ivano Cristofolini discovered that insufficient security checks in
Samba’s handling of LSA RPC calls could lead to privilege escalation
by gaining the take ownership privilege.

For the stable distribution (squeeze), this problem has been fixed in
version 3.5.6~dfsg-3squeeze8.

For the unstable distribution (sid), this problem has been fixed in
version 3.6.5-1.

We recommend that you upgrade your samba packages.
