Topic

Updated java-1.7.0-openjdk packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Description

The java-1.7.0-openjdk packages provide the OpenJDK 7 Java Runtime Environment and the OpenJDK 7 Java Software Development Kit.

Multiple flaws were discovered in the CORBA, Libraries, RMI, Serialization, and 2D components in OpenJDK. An untrusted Java application or applet could use these flaws to completely bypass Java sandbox restrictions. (CVE-2015-4835, CVE-2015-4881, CVE-2015-4843, CVE-2015-4883, CVE-2015-4860, CVE-2015-4805, CVE-2015-4844)

Multiple denial of service flaws were found in the JAXP component in OpenJDK. A specially crafted XML file could cause a Java application using JAXP to consume an excessive amount of CPU and memory when parsed. (CVE-2015-4803, CVE-2015-4893, CVE-2015-4911)

It was discovered that the Security component in OpenJDK failed to properly check if a certificate satisfied all defined constraints. In certain cases, this could cause a Java application to accept an X.509 certificate which does not meet requirements of the defined policy. (CVE-2015-4872)

Multiple flaws were found in the Libraries, 2D, CORBA, JAXP, JGSS, and RMI components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass certain Java sandbox restrictions. (CVE-2015-4806, CVE-2015-4840, CVE-2015-4882, CVE-2015-4842, CVE-2015-4734, CVE-2015-4903)

Red Hat would like to thank Andrea Palazzo of Truel IT for reporting the CVE-2015-4806 issue.

All users of java-1.7.0-openjdk are advised to upgrade to these updated packages, which resolve these issues. All running instances of OpenJDK Java must be restarted for the update to take effect.
