CVE-2014-6052 not yet assigned priority: Debian including 2 source packages (libvncserver, veyon), 10 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 10.
The HandleRFBServerMessage function in libvncclient/rfbproto.c in LibVNCServer 0.9.9 and earlier does not check certain malloc return values, which allows remote VNC servers to cause a denial of service (application crash) or possibly execute arbitrary code by specifying a large screen size in a (1) FramebufferUpdate, (2) ResizeFrameBuffer, or (3) PalmVNCReSizeFrameBuffer message.
