CVE-2018-7226

An issue was discovered in vcSetXCutTextProc() in VNConsole.c in LinuxVNC and
VNCommand from the LibVNC/vncterm distribution through 0.9.10. Missing
sanitization of the client-specified message length may cause integer overflow
or possibly have unspecified other impact via a specially crafted VNC packet.

Comment 1 Karol Babioch 2018-02-26 10:19:06 UTC

Our versions of LibVNCServer do contain the affected code, but we do not package/ship vncterm from LibVNCServer.
