CVE-2016-7118

This bug was opened only for reference. 

Neither SLE nor openSUSE are affected as AUFS is not available.


http://seclists.org/oss-sec/2016/q3/397

Marcin Szewczyk reported and diagnosed a bug in Debian's kernel
packages that allows a denial of service (crash) by local users with
access to an aufs filesystem.  The bug is in a Debian-specific patch,
not the upstream kernel or aufs code.

The current version in Debian 7 'wheezy' (3.2.81-1) and the current proposed update to Debian 8 'jessie' (3.16.36-1 are affected.

> the wheezy kernel upgrade from 3.2.78-1 to 3.2.81-1 added the SETFL
> fcntl support code (#627782) which unfortunately results in a kernel
> Oops when the fcntl is called on a directory. This breaks e.g. copying
> files from an AUFS filesystem on a remote machine using scp.
