Security fix for CVE-2015-6644

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2811 advisory.

    The eap7-jboss-ec2-eap packages provide scripts for Red Hat JBoss Enterprise Application Platform running     on the Amazon Web Services (AWS) Elastic Compute Cloud (EC2).

    With this update, the eap7-jboss-ec2-eap package has been updated to ensure compatibility with Red Hat     JBoss Enterprise Application Platform 7.0.8.

    Refer to the JBoss Enterprise Application Platform 7.0.8 Release Notes, linked to in the References     section, for information on the most significant bug fixes and enhancements included in this release.

    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 found in Jasypt that would allow an attacker to perform a timing attack on password     hash comparison. (CVE-2014-9970)

    * It was found that an information disclosure flaw in Bouncy Castle could enable a local malicious     application to gain access to user's private information. (CVE-2015-6644)

    * It was found that while parsing the SAML messages the StaxParserUtil class of Picketlink replaces     special strings for obtaining attribute values with system property. This could allow an attacker to     determine values of system properties at the attacked system by formatting the SAML request ID field to be     the chosen system property which could be obtained in the InResponseTo field in the response.
    (CVE-2017-2582)

    * It was found that when the security manager's reflective permissions, which allows it to access the     private members of the class, are granted to Hibernate Validator, a potential privilege escalation can     occur. By allowing the calling code to access those private members without the permission an attacker may     be able to validate an invalid instance and access the private member value via     ConstraintViolation#getInvalidValue(). (CVE-2017-7536)

    The CVE-2017-2582 issue was discovered by Hynek Mlnarik (Red Hat) and the CVE-2017-7536 issue was     discovered by Gunnar Morling (Red Hat).

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.

An information disclosure vulnerability was discovered in Bouncy Castle, a Java library which consists of various cryptographic algorithms. The Galois/Counter mode (GCM) implementation was missing a boundary check that could enable a local application to gain access to user's private information.

For Debian 7 'Wheezy', these problems have been fixed in version 1.44+dfsg-3.1+deb7u2.

We recommend that you upgrade your bouncycastle packages.

Quan Nguyen discovered that a missing boundary check in the Galois/Counter mode implementation of Bouncy Castle (a Java implementation of cryptographic algorithms) may result in information disclosure.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2808 advisory.
