https://www.debian.org/security/ Moritz Muehlenhoff
April 21, 2020 https://www.debian.org/security/faq
Package : openssl
CVE ID : CVE-2020-1967
Bernd Edlinger discovered that malformed data passed to the
SSL_check_chain() function during or after a TLS 1.3 handshake could
cause a NULL dereference, resulting in denial of service.
The oldstable distribution (stretch) is not affected.
For the stable distribution (buster), this problem has been fixed in
version 1.1.1d-0+deb10u3.
We recommend that you upgrade your openssl packages.
For the detailed security status of openssl please refer to
