samba - missing input sanisiting

Volker Lendecke discovered that missing range checks in Samba’s file
descriptor handling could lead to memory corruption, resulting in denial
of service.

For the oldstable distribution (lenny), this problem has been fixed in
version 3.2.5-4lenny14.

For the stable distribution (squeeze), this problem has been fixed in
version 3.5.6~dfsg-3squeeze2.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you upgrade your samba packages.
