krfb -- Possible Denial of Service or code execution via integer overflow

Albert Aastals Cid reports:

krfb embeds libvncserver which embeds liblzo2, it contains various
flaws that result in integer overflow problems.
This potentially allows a malicious application to create a
possible denial of service or code execution. Due to the need to
exploit precise details of the target architecture and threading it
is unlikely that remote code execution can be achieved in
practice.
