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 •
