*** This bug is a security vulnerability *** Public security bug reported:
The following was put out in a security advisory notice over nginx- announce's mailing list today: http://mailman.nginx.org/pipermail/nginx-announce/2018/000221.html Hello! A security issue was identified in the ngx_http_mp4_module, which might allow an attacker to cause infinite loop in a worker process, cause a worker process crash, or might result in worker process memory disclosure by using a specially crafted mp4 file (CVE-2018-16845). The issue only affects nginx if it is built with the ngx_http_mp4_module (the module is not built by default) and the "mp4" directive is used in the configuration file. Further, the attack is only possible if an attacker is able to trigger processing of a specially crafted mp4 file with the ngx_http_mp4_module. The issue affects nginx 1.1.3+, 1.0.7+. The issue is fixed in 1.15.6, 1.14.1. Patch for the issue can be found here: http://nginx.org/download/patch.2018.mp4.txt ------ Based on the version strings specified, the following Ubuntu versions of nginx are affected: * Trusty (1.4.6-1ubuntu3, 1.4.6-1ubuntu3.8) * Xenial (1.9.15-0ubuntu1, 1.10.3-0ubuntu0.16.04.2) * Bionic (1.14.0-0ubuntu1, 1.14.0-0ubuntu1.1) * Cosmic (1.15.0-0ubuntu1, 1.15.0-0ubuntu2) * Disco (1.15.0-0ubuntu1, 1.15.0-0ubuntu3) ** Affects: nginx (Ubuntu) Importance: Medium Assignee: Thomas Ward (teward) Status: Confirmed ** Affects: nginx (Ubuntu Trusty) Importance: Medium Status: Confirmed ** Affects: nginx (Ubuntu Xenial) Importance: Medium Status: Confirmed ** Affects: nginx (Ubuntu Bionic) Importance: Medium Status: Confirmed ** Affects: nginx (Ubuntu Cosmic) Importance: Medium Status: Confirmed ** Affects: nginx (Ubuntu Disco) Importance: Medium Assignee: Thomas Ward (teward) Status: Confirmed ** Changed in: nginx (Ubuntu) Status: New => Confirmed ** CVE added: https://cve.mitre.org/cgi-bin/cvename.cgi?name=2018-16845 ** Also affects: nginx (Ubuntu Trusty) Importance: Undecided Status: New ** Also affects: nginx (Ubuntu Disco) Importance: Undecided Status: Confirmed ** Also affects: nginx (Ubuntu Cosmic) Importance: Undecided Status: New ** Also affects: nginx (Ubuntu Xenial) Importance: Undecided Status: New ** Also affects: nginx (Ubuntu Bionic) Importance: Undecided Status: New ** Changed in: nginx (Ubuntu Cosmic) Status: New => Confirmed ** Changed in: nginx (Ubuntu Bionic) Status: New => Confirmed ** Changed in: nginx (Ubuntu Xenial) Status: New => Confirmed ** Changed in: nginx (Ubuntu Trusty) Status: New => Confirmed ** Description changed: The following was put out in a security advisory notice over nginx- announce's mailing list today: + + http://mailman.nginx.org/pipermail/nginx-announce/2018/000221.html Hello!
