TigerVNC version prior to 1.10.1 is vulnerable to stack buffer overflow,
which could be triggered from CMsgReader::readSetCursor. This vulnerability
occurs due to insufficient sanitization of PixelFormat. Since remote
attacker can choose offset from start of the buffer to start writing his
values, exploitation of this vulnerability could potentially result into
remote code execution. This attack appear to be exploitable via network
connectivity.
