What is CVE-2017-5884?

The gtk-vnc library, prior to version 0.7.0, is susceptible to a buffer overflow vulnerability due to improper boundary checks in subrectangle-containing tiles.

The exploitation of this vulnerability could lead to arbitrary code execution on the client side, posing significant security risks for users of the affected versions.
