Vulnerability from variot

nginx before versions 1.15.6, 1.14.1 has a vulnerability 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. 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. nginx Contains an information disclosure vulnerability.Information obtained and denial of service (DoS) May be in a state. nginx is prone to multiple denial-of-service vulnerabilities. Attackers can exploit these issues to cause denial-of-service conditions. Versions prior to nginx 1.15.6 and 1.14.1 are vulnerable. nginx is a lightweight web server/reverse proxy server and email (IMAP/POP3) proxy server developed by Russian programmer Igor Sysoev. The vulnerability is caused by the program not processing MP4 files correctly.

For the stable distribution (stretch), these problems have been fixed in version 1.10.3-1+deb9u2.

We recommend that you upgrade your nginx packages.

For the detailed security status of nginx please refer to its security tracker page at: https://security-tracker.debian.org/tracker/nginx

    "data": "nginx before versions 1.15.6, 1.14.1 has a vulnerability 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. 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. nginx Contains an information disclosure vulnerability.Information obtained and denial of service (DoS) May be in a state. nginx is prone to multiple denial-of-service vulnerabilities. \nAttackers can exploit these issues to cause denial-of-service conditions. \nVersions prior to nginx 1.15.6 and 1.14.1 are vulnerable. nginx is a lightweight web server/reverse proxy server and email (IMAP/POP3) proxy server developed by Russian programmer Igor Sysoev. The vulnerability is caused by the program not processing MP4 files correctly. \n\nFor the stable distribution (stretch), these problems have been fixed in\nversion 1.10.3-1+deb9u2. \n\nWe recommend that you upgrade your nginx packages. \n\nFor the detailed security status of nginx please refer to\nits security tracker page at:\nhttps://security-tracker.debian.org/tracker/nginx\n\nFurther information about Debian Security Advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://www.debian.org/security/\n\nMailing list: debian-security-announce@lists.debian.org\n-----BEGIN PGP SIGNATURE-----\n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\nK2fAQq6MD37FTHAghC243ZqqcRJDoDXtKfvKm8Zt3ZUnX3XUqVg=3QLE\n-----END PGP SIGNATURE-----\n. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA256\n\n=====================================================================\n                   Red Hat Security Advisory\n\nSynopsis:          Important: rh-nginx18-nginx security update\nAdvisory ID:       RHSA-2018:3652-01\nProduct:           Red Hat Software Collections\nAdvisory URL:      https://access.redhat.com/errata/RHSA-2018:3652\nIssue date:        2018-11-26\nCVE Names:         CVE-2018-16845 \n=====================================================================\n\n1.
