[3.7] libvncserver: Improper input sanitization in rfbProcessClientNormalMessage in rfbserver.c ((CVE-2018-7225)
An issue was discovered in LibVNCServer through 0.9.11.
rfbProcessClientNormalMessage() in rfbserver.c does not sanitize
msg.cct.length, leading to access
to uninitialized and potentially sensitive data or possibly unspecified
other impact (e.g., an integer overflow) via specially crafted VNC
packets.
