CVE-2023-24534

HTTP and MIME header parsing can allocate large amounts of memory, even
when parsing small inputs, potentially leading to a denial of service.
Certain unusual patterns of input data can cause the common function used
to parse HTTP and MIME headers to allocate substantially more memory than
required to hold the parsed headers. An attacker can exploit this behavior
to cause an HTTP server to allocate large amounts of memory from a small
request, potentially leading to memory exhaustion and a denial of service.
With fix, header parsing now correctly allocates only the memory required
to hold parsed headers.
