Overview
Affected versions of this package are vulnerable to Stack-based Buffer Overflow due to handling large HTTP file transfers and the HTTP response body limit has been increased. An attacker can cause a denial of service by sending specially crafted large HTTP responses that trigger a stack overflow.
Note:
This is only exploitable if the HTTP response body limit is increased and http-body-printable logging is enabled.
Workaround
This vulnerability can be mitigated by using default HTTP response body limits and/or disabling http-body-printable logging.
