Package        : pptpd 
Vulnerability  : programming error
Problem-Type   : remote
Debian-specific: no
CVE ID         : CVE-2007-0244

A regression in the handling of out-of-order sequence numbers of some
MPPE implementations was fixed. For reference the original advisory 
below:

It was discovered that the PoPToP Point to Point Tunneling Server
contains a programming error, which allows the tear-down of a PPTP
connection through a malformed GRE packet, resulting in denial of
service.

The oldstable distribution (sarge) is not affected by this problem.

For the stable distribution (etch) this problem has been fixed in
version 1.3.0-2etch2.

For the unstable distribution (sid) this problem has been fixed in
version 1.3.4-1.

We recommend that you upgrade your pptpd packages.
