  • CVE-2016-7425

    Marco Grassi discovered a buffer overflow in the arcmsr SCSI driver which may result in local denial of service, or potentially, arbitrary code execution.

Additionally this update fixes a regression introduced in DSA-3616-1 causing iptables performance issues (cf. Debian Bug #831014).

For the stable distribution (jessie), these problems have been fixed in version 3.16.36-1+deb8u2.

We recommend that you upgrade your linux packages.
