Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-27784)
