Package        : libvncserver
CVE ID         : CVE-2016-9941 CVE-2016-9942
Debian Bug     : 850007 850008

It was discovered that libvncserver, a collection of libraries used to
implement VNC/RFB clients and servers, incorrectly processed incoming
network packets. This resulted in several heap-based buffer overflows,
allowing a rogue server to either cause a DoS by crashing the client,
or potentially execute arbitrary code on the client side.

For the stable distribution (jessie), these problems have been fixed in
version 0.9.9+dfsg2-6.1+deb8u2.

For the testing (stretch) and unstable (sid) distributions, these
problems have been fixed in version 0.9.11+dfsg-1.

We recommend that you upgrade your libvncserver packages.
