Description
A flaw was found in curl. When an application configures libcurl to use HTTP/2 server push and the amount of received headers for the push surpasses the maximum allowed limit, libcurl aborts the server push. When aborting, libcurl does not free all the previously allocated headers, resulting in a memory leak.
