30 Mar 2018
Affected Packages:
Security database references:
In the Debian bugtracking system: Bug 894045.
In Mitre's CVE dictionary: CVE-2018-7225.
More information:

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.
