Descriptions

NGINX Open Source before versions 1.23.2 and 1.22.1, NGINX Open Source Subscription before versions R2 P1 and R1 P1, and NGINX Plus before versions R27 P1 and R26 P1 have a vulnerability in the module ngx_http_mp4_module that might allow a local attacker to corrupt NGINX worker memory, resulting in its termination or potential other impact using a specially crafted audio or video file. The issue affects only NGINX products that are built with the ngx_http_mp4_module, when the mp4 directive is used in the configuration file. Further, the attack is possible only if an attacker can trigger processing of a specially crafted audio or video file with the module ngx_http_mp4_module.

NGINX Open Source versiones anteriores a 1.23.2 y 1.22.1, NGINX Open Source Subscription versiones anteriores a R2 P1 y R1 P1, y NGINX Plus anteriores a R27 P1 y R26 P1, presentan una vulnerabilidad en el módulo ngx_http_mp4_module que podría permitir a un atacante local corromper la memoria del trabajador de NGINX, resultando en su terminación o cualquier otro impacto potencial usando un archivo de audio o vídeo especialmente diseñado. El problema afecta sólo a productos NGINX que son construidos con el módulo ngx_http_mp4_, cuando es usada la directiva mp4 en el archivo de configuración. Además, el ataque sólo es posible si un atacante puede desencadenar el procesamiento de un archivo de audio o vídeo especialmente diseñado con el módulo ngx_http_mp4_module

It was discovered that nginx incorrectly handled certain memory operations in the ngx_http_mp4_module module. A local attacker could possibly use this issue with a specially crafted mp4 file to cause nginx to crash, stop responding, or access arbitrary memory.
