CVE-2023-23969: Potential denial-of-service via ``Accept-Language`` headers
|
|
|
|
|
===========================================================================
|
|
|
|
|
|
|
|
|
|
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 large header values are sent.
|
|
|
|
|
|
|
|
|
|
In order to avoid this vulnerability, the ``Accept-Language`` header is now
|
|
|
|
|
parsed up to a maximum length.
