The java-1.8.0-openjdk packages provide the OpenJDK 8 Java RuntimeEnvironment and the OpenJDK 8 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 coulduse 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 inOpenJDK. A specially crafted XML file could cause a Java application usingJAXP to consume an excessive amount of CPU and memory when parsed.(CVE-2015-4803, CVE-2015-4893, CVE-2015-4911)A flaw was found in the way the Libraries component in OpenJDK handledcertificate revocation lists (CRL). In certain cases, CRL checking codecould fail to report a revoked certificate, causing the application toaccept it as trusted. (CVE-2015-4868)It was discovered that the Security component in OpenJDK failed to properlycheck if a certificate satisfied all defined constraints. In certain cases,this could cause a Java application to accept an X.509 certificate whichdoes not meet requirements of the defined policy. (CVE-2015-4872)Multiple flaws were found in the Libraries, 2D, CORBA, JAXP, JGSS, and RMIcomponents in OpenJDK. An untrusted Java application or applet could usethese 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 theCVE-2015-4806 issue.All users of java-1.8.0-openjdk are advised to upgrade to these updatedpackages, which resolve these issues. All running instances of OpenJDK Javamust be restarted for the update to take effect.
