-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: java-1.8.0-openjdk security update Advisory ID: RHSA-2015:0069-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-0069.html Issue date: 2015-01-21 CVE Names: CVE-2014-3566 CVE-2014-6549 CVE-2014-6585 CVE-2014-6587 CVE-2014-6591 CVE-2014-6593 CVE-2014-6601 CVE-2015-0383 CVE-2015-0395 CVE-2015-0407 CVE-2015-0408 CVE-2015-0410 CVE-2015-0412 CVE-2015-0437 ===================================================================== 1. Summary: Updated 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch, x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, noarch, x86_64 3. Description: The java-1.8.0-openjdk packages provide the OpenJDK 8 Java Runtime Environment and the OpenJDK 8 Java Software Development Kit. Multiple flaws were found in the way the Hotspot component in OpenJDK verified bytecode from the class files, and in the way this component generated code for bytecode. An untrusted Java application or applet could possibly use these flaws to bypass Java sandbox restrictions. (CVE-2014-6601, CVE-2015-0437) Multiple improper permission check issues were discovered in the JAX-WS, Libraries, and RMI components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions. (CVE-2015-0412, CVE-2014-6549, CVE-2015-0408) A flaw was found in the way the Hotspot garbage collector handled phantom references. An untrusted Java application or applet could use this flaw to corrupt the Java Virtual Machine memory and, possibly, execute arbitrary code, bypassing Java sandbox restrictions. (CVE-2015-0395) A flaw was found in the way the DER (Distinguished Encoding Rules) decoder in the Security component in OpenJDK handled negative length values. A specially crafted, DER-encoded input could cause a Java application to enter an infinite loop when decoded. (CVE-2015-0410) A flaw was found in the way the SSL 3.0 protocol handled padding bytes when decrypting messages that were encrypted using block ciphers in cipher block chaining (CBC) mode. This flaw could possibly allow a man-in-the-middle (MITM) attacker to decrypt portions of the cipher text using a padding oracle attack. (CVE-2014-3566) Note: This update disables SSL 3.0 by default to address this issue. The jdk.tls.disabledAlgorithms security property can be used to re-enable SSL 3.0 support if needed. For additional information, refer to the Red Hat Bugzilla bug linked to in the References section. It was discovered that the SSL/TLS implementation in the JSSE component in OpenJDK failed to properly check whether the ChangeCipherSpec was received during the SSL/TLS connection handshake. An MITM attacker could possibly use this flaw to force a connection to be established without encryption being enabled. (CVE-2014-6593) An information leak flaw was found in the Swing component in OpenJDK. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions. (CVE-2015-0407) A NULL pointer dereference flaw was found in the MulticastSocket implementation in the Libraries component of OpenJDK. An untrusted Java application or applet could possibly use this flaw to bypass certain Java sandbox restrictions. (CVE-2014-6587) Multiple boundary check flaws were found in the font parsing code in the 2D component in OpenJDK. A specially crafted font file could allow an untrusted Java application or applet to disclose portions of the Java Virtual Machine memory. (CVE-2014-6585, CVE-2014-6591) Multiple insecure temporary file use issues were found in the way the Hotspot component in OpenJDK created performance statistics and error log files. A local attacker could possibly make a victim using OpenJDK overwrite arbitrary files using a symlink attack. (CVE-2015-0383) The CVE-2015-0383 issue was discovered by Red Hat. 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. 4.
