"According to the version of the openssl111d packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerability :
- 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. Fixed in OpenSSL
1.1.1g (Affected 1.1.1d-1.1.1f).(CVE-2020-1967)
Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
