An update that fixes one vulnerability is now available.
Description:
This update for openssl-1_1 fixes the following security issue:
o 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]
