NVD Description

Note: Versions mentioned in the description apply only to the upstream nginx-mod-http-xslt-filter package and not the nginx-mod-http-xslt-filter package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

The 32-bit implementation of NGINX Open Source has a vulnerability in the ngx_http_mp4_module module, which might allow an attacker to over-read or over-write NGINX worker memory resulting in its termination, using a specially crafted MP4 file. The issue only affects 32-bit NGINX Open Source if it is built with the ngx_http_mp4_module module and the mp4 directive is used in the configuration file. Additionally, the attack is possible only if an attacker can trigger the processing of a specially crafted MP4 file with the ngx_http_mp4_module module.

Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
