A Cross-site scripting (XSS) vulnerability exists in JQuery. This flaw allows an attacker with the ability to supply input to the ‘HTML’ function to inject Javascript into the page where that input is rendered, and have it delivered by the browser. jQuery version 1.2 suffers from a cross site scripting vulnerability. • https://www.exploit-db.com/exploits/49766 https://github.com/0xAJ2K/CVE-2020-11022-CVE-2020-11023 https://github.com/ossf-cve-benchmark/CVE-2020-11022 https://github.com/Snorlyd/https-nj.gov---CVE-2020-11022 http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00067.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00085.html http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00039.html http://packetstormsecurity.com/files/162159/jQuery-1.2& • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

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 •
