qemu-kvm 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-kvm packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
