The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:1801 advisory.

    Red Hat JBoss Web Server is a fully integrated and certified set of components for hosting Java web     applications. It is comprised of the Apache HTTP Server, the Apache Tomcat Servlet container, Apache     Tomcat Connector (mod_jk), JBoss HTTP Connector (mod_cluster), Hibernate, and the Tomcat Native library.

    This release of Red Hat JBoss Web Server 3.1 Service Pack 1 serves as a replacement for Red Hat JBoss Web     Server 3.1, and includes bug fixes, which are documented in the Release Notes document linked to in the     References.

    Security Fix(es):

    * It was found that when using remote logging with log4j socket server the log4j server would deserialize     any log event received via TCP or UDP. An attacker could use this flaw to send a specially crafted log     event that, during deserialization, would execute arbitrary code in the context of the logger application.
    (CVE-2017-5645)

    * A vulnerability was discovered in tomcat's handling of pipelined requests when Sendfile was used. If     sendfile processing completed quickly, it was possible for the Processor to be added to the processor     cache twice. This could lead to invalid responses or information disclosure. (CVE-2017-5647)

    * A vulnerability was discovered in the error page mechanism in Tomcat's DefaultServlet implementation. A     crafted HTTP request could cause undesired side effects, possibly including the removal or replacement of     the custom error page. (CVE-2017-5664)

    * A vulnerability was discovered in tomcat. When running an untrusted application under a SecurityManager     it was possible, under some circumstances, for that application to retain references to the request or     response objects and thereby access and/or modify information associated with another web application.
    (CVE-2017-5648)

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

Cesar Pereida Garcia reports :

The signing function in crypto/ecdsa/ecdsa_ossl.c in certain OpenSSL versions and forks is vulnerable to timing attacks when signing with the standardized elliptic curve P-256 despite featuring constant-time curve operations and modular inversion. A software defect omits setting the BN_FLG_CONSTTIME flag for nonces, failing to take a secure code path in the BN_mod_inverse method and therefore resulting in a cache-timing attack vulnerability. A malicious user with local access can recover ECDSA P-256 private keys.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3181-1 advisory.

    Guido Vranken discovered that OpenSSL used undefined behaviour when performing pointer arithmetic. A     remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service.
    This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS as other releases were fixed in a     previous security update. (CVE-2016-2177)

    It was discovered that OpenSSL did not properly handle Montgomery multiplication, resulting in incorrect     results leading to transient failures. This issue only applied to Ubuntu 16.04 LTS, and Ubuntu 16.10.
    (CVE-2016-7055)

    It was discovered that OpenSSL did not properly use constant-time operations when performing ECDSA P-256     signing. A remote attacker could possibly use this issue to perform a timing attack and recover private     ECDSA keys. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2016-7056)

    Shi Lei discovered that OpenSSL incorrectly handled certain warning alerts. A remote attacker could     possibly use this issue to cause OpenSSL to stop responding, resulting in a denial of service.
    (CVE-2016-8610)

    Robert wicki discovered that OpenSSL incorrectly handled certain truncated packets. A remote attacker     could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2017-3731)

    It was discovered that OpenSSL incorrectly performed the x86_64 Montgomery squaring procedure. While     unlikely, a remote attacker could possibly use this issue to recover private keys. This issue only applied     to Ubuntu 16.04 LTS, and Ubuntu 16.10. (CVE-2017-3732)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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