CVE-2014-6052

Name of the Vulnerable Software and Affected Versions LibVNCServer versions 0.9.9 and earlier

Description The issue is related to the HandleRFBServerMessage function in LibVNCServer, which is associated with an error in designating the full screen. Exploitation of this issue may allow a remote attacker to access confidential data, compromise its integrity, and cause a denial of service. The vulnerability can be triggered by a remote VNC server specifying a large screen size in certain messages, potentially leading to application crashes or arbitrary code execution.

Recommendations For LibVNCServer versions 0.9.9 and earlier, consider disabling the HandleRFBServerMessage function as a temporary workaround until a patch is available. Restrict access to the LibVNCServer library to minimize the risk of exploitation. Avoid using the library with untrusted VNC servers until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
