| Descripción: | Summary:
The remote host is missing an update for the 'java-1.8.0-openjdk'
package(s) announced via the referenced advisory.
Vulnerability Insight:
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. (CVE-2014-6517)
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.
(CVE-2014-6512)
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.
