The version of Oracle Enterprise Manager Cloud Control installed on the remote host is affected by multiple vulnerabilities in Enterprise Manager Base Platform component:

  - An unspecified vulnerability in the subcomponent Networking     (jQuery) of Enterprise Manager Ops Center. Supported versions     that are affected are 12.2.2 and 12.3.3. An easy to exploit     vulnerability could allow an unauthenticated attacker with     network access via HTTP to compromise Enterprise Manager Ops     Center. A successful attacks requires human interaction and     can result in unauthorized update, insert or delete access     to some of Enterprise Manager Ops Center accessible data.
    (CVE-2015-9251)

  - An unspecified vulnerability in the subcomponent Networking     (OpenSSL) of the Enterprise Manager Ops Center. Supported     versions that are affected are 12.2.2 and 12.3.3. An easy     to exploit vulnerability could allow an unauthenticated     attacker with network access via HTTPS to compromise     Enterprise Manager Ops Center. A successful attack of this     vulnerability could result in unauthorized ability to cause     a hang or frequently repeatable crash (complete DOS) of     Enterprise Manager Ops Center. (CVE-2018-0732)

  - An unspecified vulnerability in the subcomponent Networking     (cURL) of Enterprise Manager Ops Center. Supported versions     that are affected are 12.2.2 and 12.3.3. Difficult to exploit     vulnerability allows unauthenticated attacker with network     access via HTTP to compromise Enterprise Manager Ops Center.
    A successful attack requires human interaction from a person     other than the attacker and can result in takeover of     Enterprise Manager Ops Center. (CVE-2018-1000300)

This update also contains all upstream fixes and improvements in the stable 5.1.36 release.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:3221 advisory.

    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):

    * openssl: ROHNP - Key Extraction Side Channel in Multiple Crypto Libraries (CVE-2018-0495)

    * openssl: Malicious server can send large prime to client during DH(E) TLS handshake causing the client     to hang (CVE-2018-0732)

    * openssl: Handling of crafted recursive ASN.1 structures can cause a stack overflow and resulting denial     of service (CVE-2018-0739)

    * openssl: Malformed X.509 IPAdressFamily could cause OOB read (CVE-2017-3735)

    * openssl: RSA key generation cache timing vulnerability in crypto/rsa/rsa_gen.c allows attackers to     recover private keys (CVE-2018-0737)

    For more details about the security issue(s), including the impact, a CVSS score, and other related     information, refer to the CVE page(s) listed in the References section.

    Additional Changes:

    For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.6 Release Notes     linked from the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This could be exploited in a Denial Of Service attack.(CVE-2018-0732)

Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the
_gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host.(CVE-2018-0495)

Constructed ASN.1 types with a recursive definition (such as can be found in PKCS7) could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service attack. There are no such structures used within SSL/TLS that come from untrusted sources so this is considered safe.(CVE-2018-0739)

While parsing an IPAddressFamily extension in an X.509 certificate, it is possible to do a one-byte overread. This would result in an incorrect text display of the certificate. This bug has been present since 2006.(CVE-2017-3735)

An update for openssl is now available for 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.
