"This update for openssl-1_1 fixes the security issue :

  - CVE-2021-3449: An OpenSSL TLS server may crash if sent a
    maliciously crafted renegotiation ClientHello message
    from a client. If a TLSv1.2 renegotiation ClientHello
    omits the signature_algorithms extension but includes a
    signature_algorithms_cert extension, then a NULL pointer
    dereference will result, leading to a crash and a denial
    of service attack. OpenSSL TLS clients are not impacted
    by this issue. [bsc#1183852]
