Package : libvncserver
Version : 0.9.9+dfsg-1+deb7u3
CVE ID : CVE-2018-7225
Debian Bug : 894045

libvncserver version through 0.9.11. does not sanitize msg.cct.length
which may result in access to uninitialized and potentially sensitive
data or possibly unspecified other impact (e.g., an integer overflow)
via specially crafted VNC packets.

For Debian 7 "Wheezy", these problems have been fixed in version
0.9.9+dfsg-1+deb7u3.

We recommend that you upgrade your libvncserver packages.

these updates to your system and frequently asked questions can be
