Vulnerability details
The vulnerability allows a remote attacker to cause a denial of service if image re-encoding triggers a JPEG compression error.
The vulnerability exists due to missing library error handling in winpr_convert_to_jpeg() when re-encoding image data as JPEG. A remote attacker can supply image data for clipboard conversion that, if it triggers a libjpeg compression error, invokes the default error_exit handler and terminates the client process.
