Last week it was reported that a bug in the Linux kernel could potentially allow users on a Linux-based system to gain privileges and run malicious code. The flaw was introduced during the development of the 2.6.31 kernel and affects kernels up to version 3.14.3.

For the stable distribution (wheezy), these problems have been fixed in version 3.2.57-3+deb7u1. This update also fixes a regression in the isci driver and suspend problems with certain AMD CPUs (introduced in the updated kernel from the Wheezy 7.5 point release).
For the unstable distribution (sid), these problems will be fixed soon.
We recommend that you upgrade your linux packages.
So I checked my several installation, in Debian Wheezy , apt-get update && apt-get dist-upgrade brought me to a new kernel that has the patched by Debian.
