The remote Virtuozzo host is missing a security update.
An update for openssl is now available for Red Hat Enterprise Linux 6
and Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.
OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL)
and Transport Layer Security (TLS) protocols, as well as a
full-strength general-purpose cryptography library.
Security Fix(es) :
* An integer underflow leading to an out of bounds read flaw was found
in OpenSSL. A remote attacker could possibly use this flaw to crash a
32-bit TLS/SSL server or client using OpenSSL if it used the RC4-MD5
cipher suite. (CVE-2017-3731)
* A denial of service flaw was found in the way the TLS/SSL protocol
defined processing of ALERT packets during a connection handshake. A
remote attacker could use this flaw to make a TLS/SSL server consume
an excessive amount of CPU and fail to accept connections form other

it as much as possible without introducing additional issues.
