Vulnerability Insight:
LibVNCServer is a library that allows for easy creation of VNC server or
client functionality.

An integer overflow flaw, leading to a heap-based buffer overflow, was
found in the way screen sizes were handled by LibVNCServer. A malicious VNC
server could use this flaw to cause a client to crash or, potentially,
execute arbitrary code in the client. (CVE-2014-6051)

A NULL pointer dereference flaw was found in LibVNCServer's framebuffer
setup. A malicious VNC server could use this flaw to cause a VNC client to
crash. (CVE-2014-6052)

A NULL pointer dereference flaw was found in the way LibVNCServer handled
certain ClientCutText message. A remote attacker could use this flaw to
crash the VNC server by sending a specially crafted ClientCutText message
from a VNC client. (CVE-2014-6053)

A divide-by-zero flaw was found in the way LibVNCServer handled the scaling
factor when it was set to '0'. A remote attacker could use this flaw to
crash the VNC server using a malicious VNC client. (CVE-2014-6054)

Two stack-based buffer overflow flaws were found in the way LibVNCServer
handled file transfers. A remote attacker could use this flaw to crash the
VNC server using a malicious VNC client. (CVE-2014-6055)
