Debian Security Advisory
DSA-3753-1 libvncserver -- security update
- Date Reported:
- 05 Jan 2017
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 850007, Bug 850008.
In Mitre's CVE dictionary: CVE-2016-9941, CVE-2016-9942.
- More information:
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.
