Several vulnerabilities have been discovered in the Linux kernel that
may lead to a denial of service, information leaks or privilege
escalation:
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.
