New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 5.9
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated java-1.8.0-openjdk packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6.
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.
The java-1.8.0-openjdk packages provide the OpenJDK 8 Java Runtime Environment and the OpenJDK 8 Java Software Development Kit.
It was discovered that the Libraries component in OpenJDK failed to properly handle ZIP archives that contain entries with a NUL byte used in the file names. An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions. (CVE-2014-6562)
Multiple flaws were discovered in the Libraries, 2D, and Hotspot components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass certain Java sandbox restrictions.
(CVE-2014-6506, CVE-2014-6531, CVE-2014-6502, CVE-2014-6511, CVE-2014-6504, CVE-2014-6519)
It was discovered that the StAX XML parser in the JAXP component in OpenJDK performed expansion of external parameter entities even when external entity substitution was disabled. A remote attacker could use this flaw to perform XML eXternal Entity (XXE) attack against applications using the StAX parser to parse untrusted XML documents.
It was discovered that the Hotspot component in OpenJDK failed to properly handle malformed Shared Archive files. A local attacker able to modify a Shared Archive file used by a virtual machine of a different user could possibly use this flaw to escalate their privileges. (CVE-2014-6468)
It was discovered that the DatagramSocket implementation in OpenJDK failed to perform source address checks for packets received on a connected socket. A remote attacker could use this flaw to have their packets processed as if they were received from the expected source.
It was discovered that the TLS/SSL implementation in the JSSE component in OpenJDK failed to properly verify the server identity during the renegotiation following session resumption, making it possible for malicious TLS/SSL servers to perform a Triple Handshake attack against clients using JSSE and client certificate authentication. (CVE-2014-6457)
It was discovered that the CipherInputStream class implementation in OpenJDK did not properly handle certain exceptions. This could possibly allow an attacker to affect the integrity of an encrypted stream handled by this class. (CVE-2014-6558)
The CVE-2014-6512 was discovered by Florian Weimer of Red Hat Product Security.
All users of java-1.8.0-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.
SolutionUpdate the affected packages.
