CVSS: 7.5EPSS: 0%CPEs: 46EXPL: 1CVE-2020-11996 – tomcat: specially crafted sequence of HTTP/2 requests can lead to DoS
https://notcve.org/view.php?id=CVE-2020-11996
A specially crafted sequence of HTTP/2 requests sent to Apache Tomcat 10.0.0-M1 to 10.0.0-M5, 9.0.0.M1 to 9.0.35 and 8.5.0 to 8.5.55 could trigger high CPU usage for several seconds. If a sufficient number of such requests were made on concurrent HTTP/2 connections, the server could become unresponsive. Una secuencia especialmente diseñada de peticiones HTTP/2 enviadas a Apache Tomcat versiones 10.0.0-M1 hasta 10.0.0-M5, versiones 9.0.0.M1 hasta 9.0.35 y versiones 8.5.0 hasta 8.5.55, podría desencadenar un uso elevado de la CPU por varios segundos. Si se hacen una cantidad suficiente de tales peticiones en conexiones HTTP/2 concurrentes, el servidor podría dejar de responder • https://github.com/rusakovichma/tomcat-embed-core-9.0.31-CVE-2020-11996 http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00072.html https://lists.apache.org/thread.html/r2529016c311ce9485e6f173446d469600fdfbb94dccadfcd9dfdac79%40%3Cusers.tomcat.apache.org%3E https://lists.apache.org/thread.html/r3ea96d8f36dd404acce83df8aeb22a9e807d6c13ca9c5dec72f872cd%40%3Cnotifications.ofbiz.apache.org%3E https://lists.apache.org/thread.html/r5541ef6b6b68b49f76fc4c45695940116da2b • CWE-400: Uncontrolled Resource Consumption •
CVSS: 5.5EPSS: 0%CPEs: 2EXPL: 1CVE-2020-10769 – kernel: Buffer over-read in crypto_authenc_extractkeys() when a payload longer than 4 bytes is not aligned.
https://notcve.org/view.php?id=CVE-2020-10769
A buffer over-read flaw was found in RH kernel versions before 5.0 in crypto_authenc_extractkeys in crypto/authenc.c in the IPsec Cryptographic algorithm's module, authenc. When a payload longer than 4 bytes, and is not following 4-byte alignment boundary guidelines, it causes a buffer over-read threat, leading to a system crash. This flaw allows a local attacker with user privileges to cause a denial of service. Se encontró un defecto de lectura excesiva del búfer en el kernel de RH versiones anteriores a 5.0, en la función crypto_authenc_extractkeys en el archivo crypto/authenc.c en el módulo del algoritmo Criptográfico IPsec, authenc. Cuando una carga útil de más de 4 bytes y no sigue las pautas de límites de alineación de 4 bytes, esto causa una amenaza de lectura excesiva del búfer, conllevando a un bloqueo del sistema. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00009.html https://bugzilla.redhat.com/show_bug.cgi?id=1708775%3B https://lkml.org/lkml/2019/1/21/675 https://www.oracle.com/security-alerts/cpuApr2021.html https://access.redhat.com/security/cve/CVE-2020-10769 https://bugzilla.redhat.com/show_bug.cgi?id=1708775 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
