Package : libvncserver
Version : 0.9.9+dfsg-1+deb7u2
CVE IDs : CVE-2016-9941, CVE-2016-9942
Debian Bugs : #850007, #850008
It was discovered that there were two vulnerabilities in libvncserver, a
library to create/embed a VNC server:
CVE-2016-9941: Fix a heap-based buffer overflow that allows remote servers
to cause a denial of service via a crafted FramebufferUpdate message
containing a subrectangle outside of the drawing area.
CVE-2016-9942: Fix a heap-based buffer overflow that allow remote servers
to cause a denial of service via a crafted FramebufferUpdate message with
the "Ultra" type tile such that the LZO decompressed payload exceeds the
size of the tile dimensions.
For Debian 7 "Wheezy", these issues have been fixed in libvncserver version
0.9.9+dfsg-1+deb7u2.
We recommend that you upgrade your libvncserver packages.
