"According to the versions of the openssl098e package installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - An integer overflow flaw, leading to a buffer overflow,
    was found in the way the EVP_EncryptUpdate() function
    of OpenSSL parsed very large amounts of input data. A
    remote attacker could use this flaw to crash an
    application using OpenSSL or, possibly, execute
    arbitrary code with the permissions of the user running
    that application.(CVE-2016-2106)

  - A denial of service flaw was found in the way OpenSSL
    parsed certain ASN.1-encoded data from BIO (OpenSSL's
    I/O abstraction) inputs. An application using OpenSSL
    that accepts untrusted ASN.1 BIO input could be forced
    to allocate an excessive amount of data.(CVE-2016-2109)

  - The X509_cmp_time function in crypto/x509/x509_vfy.c in
    OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1
    before 1.0.1n, and 1.0.2 before 1.0.2b allows remote
    attackers to cause a denial of service (out-of-bounds
    read and application crash) via a crafted length field
    in ASN1_TIME data, as demonstrated by an attack against
    a server that supports client authentication with a
    custom verification callback.(CVE-2015-1789)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
