HIGH

During an upload, curl mishandles HTTP/2 RST_STREAM received from the server (with reason HTTP_1_1_REQUIRED or REFUSED_STREAM) leading to a use after free of a struct Curl_easy object.

Weakness

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
