========================================================================== Ubuntu Security Notice USN-3171-1 January 11, 2017
libvncserver vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.10 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in LibVNCServer.
Software Description: - libvncserver: vnc server library
Details:
Josef Gajdusek discovered that the LibVNCServer client library incorrectly handled certain FrameBufferUpdate messages. If a user were tricked into connecting to a malicious server, an attacker could use this issue to cause a denial of service, or possibly execute arbitrary code. (CVE-2016-9941, CVE-2016-9942)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.10: libvncclient1 0.9.10+dfsg-3ubuntu0.16.10.1 libvncserver1 0.9.10+dfsg-3ubuntu0.16.10.1
Ubuntu 16.04 LTS: libvncclient1 0.9.10+dfsg-3ubuntu0.16.04.1 libvncserver1 0.9.10+dfsg-3ubuntu0.16.04.1
Ubuntu 14.04 LTS: libvncserver0 0.9.9+dfsg-1ubuntu1.2
Ubuntu 12.04 LTS: libvncserver0 0.9.8.2-2ubuntu1.2
In general, a standard system update will make all the necessary changes.
