{"id":"AZL-80777","summary":"CVE-2026-27784 affecting package nginx for versions less than 1.28.3-1","details":"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. \n\n\nNote: Software versions which have reached End of Technical Support (EoTS) are not evaluated.","modified":"2026-08-28T17:47:54.791523058Z","published":"2026-03-24T15:16:33Z","upstream":["CVE-2026-27784"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27784"}],"affected":[{"package":{"name":"nginx","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/nginx"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.28.3-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-80777.json"}}],"schema_version":"1.9.0"}
