Description

nginx contains an overflow condition in the ngx_http_parse_chunked() function in /http/ngx_http_parse.c. The issue is triggered as user-supplied input is not properly validated when handling a specially crafted request. This may allow a remote attacker to cause a stack-based buffer overflow in a worker process, resulting in a denial of service or potentially allowing the execution of arbitrary code.
