CVE-2020-13935 – tomcat: multiple requests with invalid payload length in a WebSocket frame could lead to DoS
https://notcve.org/view.php?id=CVE-2020-13935
The payload length in a WebSocket frame was not correctly validated in Apache Tomcat 10.0.0-M1 to 10.0.0-M6, 9.0.0.M1 to 9.0.36, 8.5.0 to 8.5.56 and 7.0.27 to 7.0.104. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service. La longitud de la carga útil en una trama de WebSocket no fue comprobada correctamente en Apache Tomcat versiones 10.0.0-M1 hasta 10.0.0-M6, versiones 9.0.0.M1 hasta 9.0.36, versiones 8.5.0 hasta 8.5.56 y versiones 7.0.27 hasta 7.0. 104. Las longitudes de carga útil no válidas podrían desencadenar un bucle infinito. • https://github.com/RedTeamPentesting/CVE-2020-13935 https://github.com/aabbcc19191/CVE-2020-13935 http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00084.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00088.html https://kc.mcafee.com/corporate/index?page=content&id=SB10332 https://lists.apache.org/thread.html/r4e5d3c09f4dd2923191e972408b40fb8b42dbff0bc7904d44b651e50%40%3Cusers.tomcat.apache.org%3E https://lists.apache.org/thread.html/rd48c72bd3255bda87564d4da3791517c074d94f8a701f93b85752651%40%3Cannounce& • CWE-400: Uncontrolled Resource Consumption CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVE-2020-13934 – tomcat: OutOfMemoryException caused by HTTP/2 connection leak could lead to DoS

CVE-2020-15358 – sqlite: heap-based buffer overflow in multiSelectOrderBy due to mishandling of query-flattener optimization in select.c
https://notcve.org/view.php?id=CVE-2020-15358
In SQLite before 3.32.3, select.c mishandles query-flattener optimization, leading to a multiSelectOrderBy heap overflow because of misuse of transitive properties for constant propagation. En SQLite versiones anteriores a 3.32.3, el archivo select.c maneja inapropiadamente la optimización query-flattener, conllevando a un desbordamiento de la pila de multiSelectOrderBy debido al uso inapropiado de las propiedades transitivas para la propagación constante A heap buffer overflow was found in SQLite in the query flattening optimization technique. This flaw allows an attacker to execute SQL statements to crash the application, resulting in a denial of service. • http://seclists.org/fulldisclosure/2020/Dec/32 http://seclists.org/fulldisclosure/2020/Nov/19 http://seclists.org/fulldisclosure/2020/Nov/20 http://seclists.org/fulldisclosure/2020/Nov/22 http://seclists.org/fulldisclosure/2021/Feb/14 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://security.gentoo.org/glsa/202007-26 https://security.netapp.com/advisory/ntap-20200709-0001 https://support.apple.com/kb/HT211843 https://support.apple.com/kb/HT211844 https • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
