The remote host is affected by the vulnerability described in GLSA-201903-10 (OpenSSL: Multiple vulnerabilities)
Multiple vulnerabilities have been discovered in OpenSSL. Please review the CVE identifiers referenced below for details.
Impact :
A remote attacker to obtain sensitive information, caused by the failure to immediately close the TCP connection after the hosts encounter a zero-length record with valid padding.
A local attacker could run a malicious process next to legitimate processes using the architecture’s parallel thread running capabilities to leak encrypted data from the CPU’s internal processes.
Workaround :
There is no known workaround at this time.
