CVSS: 9.8EPSS: 4%CPEs: 9EXPL: 0CVE-2016-0746 – nginx: use-after-free during CNAME response processing in resolver
https://notcve.org/view.php?id=CVE-2016-0746
Use-after-free vulnerability in the resolver in nginx 0.6.18 through 1.8.0 and 1.9.x before 1.9.10 allows remote attackers to cause a denial of service (worker process crash) or possibly have unspecified other impact via a crafted DNS response related to CNAME response processing. Vulnerabilidad de uso de memoria previamente liberada en la resolución en nginx, de la versión 0.6.18 hasta la 1.8.0 y versiones 1.9.x anteriores a la 1.9.10, permite que atacantes remotos provoquen una denegación de servicio (cierre inesperado del proceso worker) o que tengan otro tipo de impacto sin especificar mediante una respuesta DNS relacionada con el procesamiento de respuestas CNAME. A use-after-free flaw was found in the way nginx resolved certain CNAME DNS records. An attacker able to manipulate DNS responses received by nginx could use this flaw to cause a worker process to crash or, possibly, execute arbitrary code if nginx enabled the resolver in its configuration. • http://lists.opensuse.org/opensuse-updates/2016-02/msg00042.html http://mailman.nginx.org/pipermail/nginx/2016-January/049700.html http://seclists.org/fulldisclosure/2021/Sep/36 http://www.debian.org/security/2016/dsa-3473 http://www.securitytracker.com/id/1034869 http://www.ubuntu.com/usn/USN-2892-1 https://access.redhat.com/errata/RHSA-2016:1425 https://bto.bluecoat.com/security-advisory/sa115 https://bugzilla.redhat.com/show_bug.cgi?id=1302588 https://security.gentoo • CWE-416: Use After Free •
CVSS: 5.3EPSS: 1%CPEs: 10EXPL: 0CVE-2016-0747 – nginx: Insufficient limits of CNAME resolution in resolver
https://notcve.org/view.php?id=CVE-2016-0747
The resolver in nginx before 1.8.1 and 1.9.x before 1.9.10 does not properly limit CNAME resolution, which allows remote attackers to cause a denial of service (worker process resource consumption) via vectors related to arbitrary name resolution. El traductor de direcciones en nginx en versiones anteriores a 1.8.1 y 1.9.x en versiones anteriores a 1.9.10 no limita correctamente la resolución CNAME, lo que permite a atacantes remotos provocar una denegación de servicio (consumo de recursos por el proceso trabajador) a través de vectores relacionados con la resolución de nombre arbitrario. It was discovered that nginx did not limit recursion when resolving CNAME DNS records. An attacker able to manipulate DNS responses received by nginx could use this flaw to cause a worker process to use an excessive amount of resources if nginx enabled the resolver in its configuration. • http://lists.opensuse.org/opensuse-updates/2016-02/msg00042.html http://mailman.nginx.org/pipermail/nginx/2016-January/049700.html http://seclists.org/fulldisclosure/2021/Sep/36 http://www.debian.org/security/2016/dsa-3473 http://www.securitytracker.com/id/1034869 http://www.ubuntu.com/usn/USN-2892-1 https://access.redhat.com/errata/RHSA-2016:1425 https://bto.bluecoat.com/security-advisory/sa115 https://bugzilla.redhat.com/show_bug.cgi?id=1302589 https://security.gentoo • CWE-400: Uncontrolled Resource Consumption •
