Описание
There is a "Use After Free" vulnerability in Qt's QHttp2ProtocolHandler in the QtNetwork module. This only affects HTTP/2 handling, HTTP handling is not affected by this at all. This happens due to a race condition between how QHttp2Stream uploads the body of a
POST request and the simultaneous handling of HTTP error responses.
This issue only affects Qt 6.9.0 and has been fixed for Qt 6.9.1.
A use-after-free vulnerability has been discovered in Qt's QHttp2ProtocolHandler function. This vulnerability only affects HTTP/2 handling and is the result of a race condition between HTTP body and error response handling.
