When the library processes an HTTP/2 GOAWAY frame, it improperly handles the \"Additional Debug Data\" payload by assuming the data stream is a safely NUL-terminated C-string. Because the parser lacks strict length-boundary verification before reading this data, a remote, unauthenticated attacker can intentionally send a malformed GOAWAY frame missing the appropriate null delimiter. This causes the library to read past the end of the allocated buffer, triggering an application crash that results in a denial of service (DoS), or potentially exposing fragments of memory contents."}], "lastModified": "2026-07-15T18:20:21.237", "sourceIdentifier": "secalert@redhat.com"}
