An issue was discovered in Poppler 0.71.0. There is a reachable abort in Object.h, will lead to denial of service because EmbFile::save2 in FileSpec.cc lacks a stream check before saving an embedded file. Se ha descubierto un problema en Poppler 0.71.0. Hay un aborto alcanzable en Object.h, que conducirá a una denegación de servicio (DoS) debido a que EmbFile::save2 en FileSpec.cc carece de una comprobación de flujo antes de guardar un archivo embebido. • https://access.redhat.com/errata/RHSA-2019:2022 https://gitlab.freedesktop.org/poppler/poppler/issues/659 https://lists.debian.org/debian-lts-announce/2019/03/msg00008.html https://lists.debian.org/debian-lts-announce/2020/11/msg00014.html https://lists.debian.org/debian-lts-announce/2022/09/msg00030.html https://usn.ubuntu.com/3837-1 https://access.redhat.com/security/cve/CVE-2018-19058 https://bugzilla.redhat.com/show_bug.cgi?id=1649435 • CWE-400: Uncontrolled Resource Consumption CWE-670: Always-Incorrect Control Flow Implementation •

https://notcve.org/view.php?id=CVE-2018-16844
nginx before versions 1.15.6 and 1.14.1 has a vulnerability in the implementation of HTTP/2 that can allow for excessive CPU usage. This issue affects nginx compiled with the ngx_http_v2_module (not compiled by default) if the 'http2' option of the 'listen' directive is used in a configuration file. nginx en versiones anteriores a la 1.15.6 y 1.14.1 tiene una vulnerabilidad en la implementación de HTTP/2 que puede permitir el uso excesivo de CPU. Este problema afecta a nginx compilado con ngx_http_v2_module (no compilado por defecto) si la opción "hppt2" de la directiva "listen" se emplea en un archivo de configuración. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00035.html http://mailman.nginx.org/pipermail/nginx-announce/2018/000220.html http://seclists.org/fulldisclosure/2021/Sep/36 http://www.securityfocus.com/bid/105868 http://www.securitytracker.com/id/1042038 https://access.redhat.com/errata/RHSA-2018:3680 https://access.redhat.com/errata/RHSA-2018:3681 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16844 https://support.apple.com/kb/HT212818 https://usn.ub • CWE-400: Uncontrolled Resource Consumption •

CVSS: 8.2EPSS: 0%CPEs: 10EXPL: 0CVE-2018-16845 – nginx: Denial of service and memory disclosure via mp4 module
https://notcve.org/view.php?id=CVE-2018-16845
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 en versiones anteriores a la 1.15.6 y 1.14.1 tiene una vulnerabilidad en ngx_http_mp4_module, que podría permitir que un atacante provoque un bucle infinito en un proceso worker o resulte en la divulgación de la memoria del proceso mediante el uso de un archivo mp4 especialmente manipulado. El problema solo afecta a nginx si está incluido con ngx_http_mp4_module (el módulo no está incluido por defecto) y se emplea la directiva .mp4 en el archivo de configuración. Además, el atacante solo es posible si un atacante puede desencadenar el procesado de un archivo mp4 especialmente manipulado con ngx_http_mp4_module. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00035.html http://mailman.nginx.org/pipermail/nginx-announce/2018/000221.html http://seclists.org/fulldisclosure/2021/Sep/36 http://www.securityfocus.com/bid/105868 http://www.securitytracker.com/id/1042039 https://access.redhat.com/errata/RHSA-2018:3652 https://access.redhat.com/errata/RHSA-2018:3653 https://access.redhat.com/errata/RHSA-2018:3680 https://access.redhat.com/errata/RHSA-2018:3681 https://bugzilla.r • CWE-201: Insertion of Sensitive Information Into Sent Data CWE-400: Uncontrolled Resource Consumption CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVSS: 9.8EPSS: 0%CPEs: 13EXPL: 0CVE-2018-16395 – ruby: OpenSSL::X509:: Name equality check does not work correctly
https://notcve.org/view.php?id=CVE-2018-16395
An issue was discovered in the OpenSSL library in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. When two OpenSSL::X509::Name objects are compared using ==, depending on the ordering, non-equal objects may return true. When the first argument is one character longer than the second, or the second argument contains a character that is one less than a character in the same position of the first argument, the result of == will be true. This could be leveraged to create an illegitimate certificate that may be accepted as legitimate and then used in signing or encryption operations.
