Vulnerability from variot
njs through 0.4.3, used in NGINX, has an out-of-bounds read in njs_lvlhsh_level_find in njs_lvlhsh.c. njs Exists in an out-of-bounds read vulnerability.Service operation interruption (DoS) It may be put into 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. The njs_lvlhsh_level_find of the njs_lvlhsh.c file in njs 0.4.3 and earlier versions (used in NGINX) has a buffer error vulnerability. This vulnerability stems from the incorrect verification of data boundaries when the network system or product performs operations on the memory, resulting in incorrect read and write operations to other associated memory locations. Attackers can exploit this vulnerability to cause buffer overflow or heap overflow, etc
