https://notcve.org/view.php?id=CVE-2021-3737
A flaw was found in python. An improperly handled HTTP response in the HTTP client code of python may allow a remote attacker, who controls the HTTP server, to make the client script enter an infinite loop, consuming CPU time. The highest threat from this vulnerability is to system availability. Se ha encontrado un fallo en python. Una respuesta HTTP manejada inapropiadamente en el código del cliente HTTP de python puede permitir a un atacante remoto, que controle el servidor HTTP, hacer que el script del cliente entre en un bucle infinito, consumiendo tiempo de CPU. • https://bugs.python.org/issue44022 https://bugzilla.redhat.com/show_bug.cgi?id=1995162 https://github.com/python/cpython/pull/25916 https://github.com/python/cpython/pull/26503 https://lists.debian.org/debian-lts-announce/2023/05/msg00024.html https://lists.debian.org/debian-lts-announce/2023/06/msg00039.html https://python-security.readthedocs.io/vuln/urllib-100-continue-loop.html https://security.netapp.com/advisory/ntap-20220407-0009 https://ubuntu.com/security/CVE-2021-3737 • CWE-400: Uncontrolled Resource Consumption CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

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') •
