"Richard van Eeden of Microsoft Vulnerability Research discovered that
Samba, a SMB/CIFS file, print, and login server for Unix, contains a
flaw in the netlogon server code which allows remote code execution
with root privileges from an unauthenticated connection.

For the oldstable distribution (squeeze), this problem has been fixed
in version 2:3.5.6~dfsg-3squeeze12.

For the stable distribution (wheezy), this problem has been fixed in
version 2:3.6.6-6+deb7u5.

We recommend that you upgrade your samba packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
