CVE-2020-10683 – dom4j: XML External Entity vulnerability in default SAX parser
https://notcve.org/view.php?id=CVE-2020-10683
dom4j before 2.0.3 and 2.1.x before 2.1.3 allows external DTDs and External Entities by default, which might enable XXE attacks. However, there is popular external documentation from OWASP showing how to enable the safe, non-default behavior in any application that uses dom4j. dom4j versiones anteriores a 2.0.3 y versiones 2.1.x anteriores a 2.1.3, permite DTDs y External Entities por defecto, lo que podría permitir ataques de tipo XXE. Sin embargo, existe una documentación externa popular de OWASP que muestra cómo habilitar el comportamiento seguro no predeterminado en cualquier aplicación que use dom4j. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00061.html https://bugzilla.redhat.com/show_bug.cgi?id=1694235 https://cheatsheetseries.owasp.org/cheatsheets/XML_External_Entity_Prevention_Cheat_Sheet.html https://github.com/dom4j/dom4j/commit/a8228522a99a02146106672a34c104adbda5c658 https://github.com/dom4j/dom4j/commits/version-2.0.3 https://github.com/dom4j/dom4j/issues/87 https://github.com/dom4j/dom4j/releases/tag/version-2.1.3 https://lists.apache.org/thread.html/r51f3f9801058 • CWE-611: Improper Restriction of XML External Entity Reference •

CVE-2020-1967 – Segmentation fault in SSL_check_chain
https://notcve.org/view.php?id=CVE-2020-1967
Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signature_algorithms_cert" TLS extension. The crash occurs if an invalid or unrecognised signature algorithm is received from the peer. This could be exploited by a malicious peer in a Denial of Service attack. OpenSSL version 1.1.1d, 1.1.1e, and 1.1.1f are affected by this issue. This issue did not affect OpenSSL versions prior to 1.1.1d. • https://github.com/irsl/CVE-2020-1967 http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00011.html http://packetstormsecurity.com/files/157527/OpenSSL-signature_algorithms_cert-Denial-Of-Service.html http://seclists.org/fulldisclosure/2020/May/5 http://www.openwall.com/lists/oss-security/2020/04/22/2 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=eb563247aef3e83dda7679c43f9649270462e5b1 https:/ • CWE-476: NULL Pointer Dereference •
