CVSS: 9.8EPSS: 1%CPEs: 7EXPL: 0CVE-2020-26154 – libproxy: sending more than 102400 bytes in PAC without a Content-Length present could result in buffer overflow
https://notcve.org/view.php?id=CVE-2020-26154
url.cpp in libproxy through 0.4.15 is prone to a buffer overflow when PAC is enabled, as demonstrated by a large PAC file that is delivered without a Content-length header. El archivo url.cpp en libproxy versiones hasta 0.4.15, es propenso a un desbordamiento del búfer cuando PAC está habilitado, como es demostrado por un archivo PAC grande que es entregado sin un encabezado Content-length • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00030.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00033.html https://bugs.debian.org/968366 https://github.com/libproxy/libproxy/pull/126 https://lists.debian.org/debian-lts-announce/2020/11/msg00024.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3BID3HVHAF6DA3YJOFDBSAZSMR3ODNIW https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WZVZ • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-121: Stack-based Buffer Overflow •

An exploitable denial of service vulnerability exists in the atftpd daemon functionality of atftp 0.7.git20120829-3.1+b1. A specially crafted sequence of RRQ-Multicast requests trigger an assert() call resulting in denial-of-service. An attacker can send a sequence of malicious packets to trigger this vulnerability. Se presenta una vulnerabilidad de denegación de servicio explotable en la funcionalidad del demonio de atftpd de atftp versión 0.7.git20120829-3.1+b1. Una secuencia especialmente diseñada de peticiones RRQ-Multicast desencadena una llamada a la función assert() que resulta en una denegación de servicio. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00058.html https://lists.debian.org/debian-lts-announce/2021/11/msg00014.html https://talosintelligence.com/vulnerability_reports/TALOS-2020-1029 • CWE-617: Reachable Assertion •
CVSS: 7.5EPSS: 0%CPEs: 11EXPL: 1CVE-2020-25219 – libproxy: uncontrolled recursion via an infinite stream response leading to stack exhaustion
https://notcve.org/view.php?id=CVE-2020-25219
url::recvline in url.cpp in libproxy 0.4.x through 0.4.15 allows a remote HTTP server to trigger uncontrolled recursion via a response composed of an infinite stream that lacks a newline character. This leads to stack exhaustion. La función url::recvline en el archivo url.cpp en libproxy versiones 0.4.x hasta 0.4.15, permite a un servidor HTTP remoto activar una recursividad no controlada por medio de una respuesta compuesta por una transmisión infinita que carece de un carácter newline. Esto conlleva al agotamiento de la pila. A flaw was found in libproxy in versions 0.4 through 0.4.15. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00030.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00033.html https://github.com/libproxy/libproxy/issues/134 https://lists.debian.org/debian-lts-announce/2020/09/msg00012.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CNID6EZVOVH7EZB7KFU2EON54CFDIVUR https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JF5JSONJNO64ARWRVOS6K6HSIPHEF3H2 https://lists • CWE-674: Uncontrolled Recursion •

An issue was discovered in Flask-CORS (aka CORS Middleware for Flask) before 3.0.9. It allows ../ directory traversal to access private resources because resource matching does not ensure that pathnames are in a canonical format. Se detectó un problema en Flask-CORS (también se conoce como CORS Middleware para Flask) versiones anteriores a 3.0.9. Permite que un salto de directorios ../ acceda a recursos privados porque la coincidencia de recursos no garantiza que los nombres de ruta estén en un formato canónico • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00039.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00048.html https://github.com/corydolphin/flask-cors/releases/tag/3.0.9 https://www.debian.org/security/2020/dsa-4775 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

The Kleopatra component before 3.1.12 (and before 20.07.80) for GnuPG allows remote attackers to execute arbitrary code because openpgp4fpr: URLs are supported without safe handling of command-line options. The Qt platformpluginpath command-line option can be used to load an arbitrary DLL. El componente Kleopatra versiones anteriores a 3.1.12 (y versiones anteriores a 20.07.80) para GnuPG, permite a atacantes remotos ejecutar código arbitrario porque las URL openpgp4fpr: son compatibles sin un manejo seguro de las opciones de la línea de comandos.
