ppp - security update

A vulnerability was discovered in ppp, an implementation of the
Point-to-Point Protocol: an integer overflow in the routine
responsible for parsing user-supplied options potentially allows a
local attacker to gain root privileges.

For the stable distribution (wheezy), this problem has been fixed in
version 2.4.5-5.1+deb7u1.

For the upcoming stable distribution (jessie) and unstable
distribution (sid), this problem has been fixed in version 2.4.6-3.

We recommend that you upgrade your ppp packages.
