[4.1.x] Fixed CVE-2023-23969 -- Prevented DoS with pathological values for Accept-Language.
The parsed values of Accept-Language headers are cached in order to avoid repetitive parsing. This leads to a potential denial-of-service vector via excessive memory usage if the raw value of Accept-Language headers is very large. Accept-Language headers are now limited to a maximum length in order to avoid this issue.
