CVSS: 7.5EPSS: 2%CPEs: 37EXPL: 0CVE-2021-42340 – DoS via memory leak with WebSocket connections
https://notcve.org/view.php?id=CVE-2021-42340
The fix for bug 63362 present in Apache Tomcat 10.1.0-M1 to 10.1.0-M5, 10.0.0-M1 to 10.0.11, 9.0.40 to 9.0.53 and 8.5.60 to 8.5.71 introduced a memory leak. The object introduced to collect metrics for HTTP upgrade connections was not released for WebSocket connections once the connection was closed. This created a memory leak that, over time, could lead to a denial of service via an OutOfMemoryError. La corrección del bug 63362 presente en Apache Tomcat versiones 10.1.0-M1 hasta 10.1.0-M5, versiones 10.0.0-M1 hasta 10.0.11, versiones 9.0.40 hasta 9.0.53 y versiones 8.5.60 hasta 8.5.71, introducía una pérdida de memoria. El objeto introducido para recopilar métricas para las conexiones de actualización HTTP no se liberaba para las conexiones WebSocket una vez que se cerraba la conexión. • https://kc.mcafee.com/corporate/index?page=content&id=SB10379 https://lists.apache.org/thread.html/r8097a2d1550aa78e585fc77e602b9046e6d4099d8d132497c5387784%40%3Ccommits.myfaces.apache.org%3E https://lists.apache.org/thread.html/r83a35be60f06aca2065f188ee542b9099695d57ced2e70e0885f905c%40%3Cannounce.tomcat.apache.org%3E https://security.gentoo.org/glsa/202208-34 https://security.netapp.com/advisory/ntap-20211104-0001 https://www.debian.org/security/2021/dsa-5009 https://www.oracle.com/security-alerts/cpuapr2022.html https://www • CWE-772: Missing Release of Resource after Effective Lifetime •
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') •
