Package : qemu
Version : 1.1.2+dfsg-6+deb7u15
CVE ID : CVE-2016-7116
Debian Bug : 836502

Quick Emulator(Qemu) built with the VirtFS, host directory sharing via Plan 9
File System(9pfs) support, is vulnerable to a directory/path traversal issue.
It could occur while creating or accessing files on a shared host directory.

A privileged user inside guest could use this flaw to access undue files on the
host.

For Debian 7 "Wheezy", these problems have been fixed in version
1.1.2+dfsg-6+deb7u15.

We recommend that you upgrade your qemu packages.

Further information about Debian LTS security advisories, how to apply
these updates to your system and frequently asked questions can be
