CVSS: 7.5EPSS: 1%CPEs: 27EXPL: 0CVE-2021-37137 – netty-codec: SnappyFrameDecoder doesn't restrict chunk length and may buffer skippable chunks in an unnecessary way
https://notcve.org/view.php?id=CVE-2021-37137
The Snappy frame decoder function doesn't restrict the chunk length which may lead to excessive memory usage. Beside this it also may buffer reserved skippable chunks until the whole chunk was received which may lead to excessive memory usage as well. This vulnerability can be triggered by supplying malicious input that decompresses to a very big size (via a network stream or a file) or by sending a huge skippable chunk. La función Snappy frame decoder no restringe la longitud de los trozos, lo que puede conllevar a un uso excesivo de memoria. Además, también puede almacenar en el búfer trozos omitibles reservados hasta que se reciba el trozo completo, lo que también puede conllevar a un uso excesivo de memoria. • https://github.com/netty/netty/security/advisories/GHSA-9vjp-v76f-g363 https://lists.apache.org/thread.html/r06a145c9bd41a7344da242cef07977b24abe3349161ede948e30913d%40%3Ccommits.druid.apache.org%3E https://lists.apache.org/thread.html/r5406eaf3b07577d233b9f07cfc8f26e28369e6bab5edfcab41f28abb%40%3Ccommits.druid.apache.org%3E https://lists.apache.org/thread.html/r5e05eba32476c580412f9fbdfc9b8782d5b40558018ac4ac07192a04%40%3Ccommits.druid.apache.org%3E https://lists.apache.org/thread.html/r75490c61c2cb7b6ae2c81238fd52ae13636c60435abcd732d41531a0%40%3Ccommits.druid.apache.org%3E ht • CWE-400: Uncontrolled Resource Consumption •
CVSS: 5.9EPSS: 0%CPEs: 23EXPL: 0CVE-2021-38153 – Timing Attack Vulnerability for Apache Kafka Connect and Clients
https://notcve.org/view.php?id=CVE-2021-38153
Some components in Apache Kafka use `Arrays.equals` to validate a password or key, which is vulnerable to timing attacks that make brute force attacks for such credentials more likely to be successful. Users should upgrade to 2.8.1 or higher, or 3.0.0 or higher where this vulnerability has been fixed. The affected versions include Apache Kafka 2.0.0, 2.0.1, 2.1.0, 2.1.1, 2.2.0, 2.2.1, 2.2.2, 2.3.0, 2.3.1, 2.4.0, 2.4.1, 2.5.0, 2.5.1, 2.6.0, 2.6.1, 2.6.2, 2.7.0, 2.7.1, and 2.8.0. Algunos componentes de Apache Kafka usan "Arrays.equals" para comprender una contraseña o clave, lo cual es vulnerable a ataques de tiempo que hacen que los ataques de fuerza bruta para dichas credenciales tengan más probabilidades de éxito. Los usuarios deben actualizar a la versión 2.8.1 o superior, o a la 3.0.0 o superior, donde se ha corregido esta vulnerabilidad. • https://kafka.apache.org/cve-list https://lists.apache.org/thread.html/r26390c8b09ecfa356582d665b0c01f4cdcf16ac047c85f9f9f06a88c%40%3Cdev.kafka.apache.org%3E https://lists.apache.org/thread.html/r26390c8b09ecfa356582d665b0c01f4cdcf16ac047c85f9f9f06a88c%40%3Cusers.kafka.apache.org%3E https://lists.apache.org/thread.html/r35322aec467ddae34002690edaa4d9f16e7df9b5bf7164869b75b62c%40%3Cdev.kafka.apache.org%3E https://lists.apache.org/thread.html/r45cc0602d5f2cbb72e48896dfadf5e5b87ed85630449598b40e8f0be%40%3Cdev.kafka.apache.org%3E https://lists.apache.org/thread.html/r45c • CWE-203: Observable Discrepancy CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
CVSS: 7.5EPSS: 0%CPEs: 24EXPL: 0CVE-2021-37714 – Crafted input may cause the jsoup HTML and XML parser to get stuck, timeout, or throw unchecked exceptions
https://notcve.org/view.php?id=CVE-2021-37714
jsoup is a Java library for working with HTML. Those using jsoup versions prior to 1.14.2 to parse untrusted HTML or XML may be vulnerable to DOS attacks. If the parser is run on user supplied input, an attacker may supply content that causes the parser to get stuck (loop indefinitely until cancelled), to complete more slowly than usual, or to throw an unexpected exception. This effect may support a denial of service attack. The issue is patched in version 1.14.2. • https://github.com/jhy/jsoup/security/advisories/GHSA-m72m-mhq2-9p6c https://jsoup.org/news/release-1.14.1 https://jsoup.org/news/release-1.14.2 https://lists.apache.org/thread.html/r215009dbf7467a9f6506d0c0024cb36cad30071010e62c9352cfaaf0%40%3Cissues.maven.apache.org%3E https://lists.apache.org/thread.html/r377b93d79817ce649e9e68b3456e6f499747ef1643fa987b342e082e%40%3Cissues.maven.apache.org%3E https://lists.apache.org/thread.html/r3d71f18adb78e50f626dde689161ca63d3b7491bd9718fcddfaecba7%40%3Cissues.maven.apache.org%3E https://lists.apa • CWE-248: Uncaught Exception CWE-400: Uncontrolled Resource Consumption CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
