CVE-2016-4414

Name of the Vulnerable Software and Affected Versions Quassel versions prior to 0.12.4

Description The issue allows remote attackers to cause a denial of service, resulting in a crash due to a NULL pointer dereference. This occurs when the onReadyRead function in coreauthhandler.cpp processes invalid handshake data.

Recommendations For versions prior to 0.12.4, update to version 0.12.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the onReadyRead function until a patch is available.
