From ab06bb17dae2c7ad2f810a38f184fe4a601b6f8d Mon Sep 17 00:00:00 2001 From: Martin Weinelt Date: Wed, 22 Apr 2020 01:46:18 +0200 Subject: [PATCH] =?UTF-8?q?openssl:=201.1.1f=20=E2=86=92=201.1.1g?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes: CVE-2020-1967 Segmentation fault in SSL_check_chain (CVE-2020-1967) ===================================================== Severity: High 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. Affected OpenSSL 1.1.1 users should upgrade to 1.1.1g This issue was found by Bernd Edlinger and reported to OpenSSL on 7th April 2020. It was found using the new static analysis pass being implemented in GCC, - -fanalyzer. Additional analysis was performed by Matt Caswell and Benjamin Kaduk.
