VAR-202008-0761
Vulnerability from variot - Updated: 2023-12-18 13:42njs through 0.4.3, used in NGINX, has a use-after-free in njs_json_parse_iterator_call in njs_json.c. NGINX Used in njs Is vulnerable to the use of freed memory.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put in a state. NGINX is a lightweight web server/reverse proxy server and e-mail (IMAP/POP3) proxy server of the American NGINX company. njs is one of the scripting language components that supports extending NGINX functionality. njs_json_parse_iterator_call in the njs_json.c file in njs 0.4.3 and earlier versions (used in NGINX) has a resource management error vulnerability. This vulnerability stems from improper management of system resources (such as memory, disk space, files, etc.) by network systems or products
