Name of the Vulnerable Software and Affected Versions Deskflow versions 1.17.0 through 1.26.0.295
Description A malicious server can send an odd-length DSOP vector to the setOptions() function in src/lib/client/ServerProxy.cpp. This causes the application to read beyond the vector when a value is missing after the final option key during the call chain from PacketStreamFilter::filterEvent() to ServerProxy::handleData() and ServerProxy::parseHandshakeMessage(), resulting in a client crash.
Recommendations Update to continuous build 1.26.0.296.
