Software Description: - - openjdk-8: Open Source Java implementation Details: USN-3366-1 fixed vulnerabilities in OpenJDK 8. Unfortunately, that update introduced a regression that caused some valid JAR files to fail validation. This update fixes the problem. We apologize for the inconvenience. Original advisory details: It was discovered that the JPEGImageReader class in OpenJDK would incorrectly read unused image data. An attacker could use this to specially construct a jpeg image file that when opened by a Java application would cause a denial of service. (CVE-2017-10053) It was discovered that the JAR verifier in OpenJDK did not properly handle archives containing files missing digests. An attacker could use this to modify the signed contents of a JAR file. (CVE-2017-10067) It was discovered that integer overflows existed in the Hotspot component of OpenJDK when generating range check loop predicates. An attacker could use this to specially construct an untrusted Java application or applet that could escape sandbox restrictions and cause a denial of service or possibly execute arbitrary code. (CVE-2017-10074) It was discovered that the JavaScript Scripting component of OpenJDK incorrectly allowed access to Java APIs. An attacker could use this to specially craft JavaScript code to bypass access restrictions. (CVE-2017-10078) It was discovered that OpenJDK did not properly process parentheses in function signatures. An attacker could use this to specially construct an untrusted Java application or applet that could escape sandbox restrictions. (CVE-2017-10081) It was discovered that the ThreadPoolExecutor class in OpenJDK did not properly perform access control checks when cleaning up threads. An attacker could use this to specially construct an untrusted Java application or applet that could escape sandbox restrictions and possibly execute arbitrary code. (CVE-2017-10087) It was discovered that the ServiceRegistry implementation in OpenJDK did not perform access control checks in certain situations. An attacker could use this to specially construct an untrusted Java application or applet that escaped sandbox restrictions. (CVE-2017-10089) It was discovered that the channel groups implementation in OpenJDK did not properly perform access control checks in some situations. An attacker could use this to specially construct an untrusted Java application or applet that could escape sandbox restrictions. (CVE-2017-10090) It was discovered that the DTM exception handling code in the JAXP component of OpenJDK did not properly perform access control checks. An attacker could use this to specially construct an untrusted Java application or applet that could escape sandbox restrictions. (CVE-2017-10096) It was discovered that the JAXP component of OpenJDK incorrectly granted access to some internal resolvers. An attacker could use this to specially construct an untrusted Java application or applet that could escape sandbox restrictions. (CVE-2017-10101) It was discovered that the Distributed Garbage Collector (DGC) in OpenJDK did not properly track references in some situations. A remote attacker could possibly use this to execute arbitrary code. (CVE-2017-10102) It was discovered that the Activation ID implementation in the RMI component of OpenJDK did not properly check access control permissions in some situations. An attacker could use this to specially construct an untrusted Java application or applet that could escape sandbox restrictions. (CVE-2017-10107) It was discovered that the BasicAttribute class in OpenJDK did not properly bound memory allocation when de-serializing objects. An attacker could use this to cause a denial of service (memory consumption). (CVE-2017-10108) It was discovered that the CodeSource class in OpenJDK did not properly bound memory allocations when de-serializing object instances. An attacker could use this to cause a denial of service (memory consumption). (CVE-2017-10109) It was discovered that the AWT ImageWatched class in OpenJDK did not properly perform access control checks, An attacker could use this to specially construct an untrusted Java application or applet that could escape sandbox restrictions (CVE-2017-10110) Jackson Davis discovered that the LambdaFormEditor class in the Libraries component of OpenJDK did not correctly perform bounds checks in the permuteArgumentsForm() function. An attacker could use this to specially construct an untrusted Java application or applet that could escape sandbox restrictions and possibly execute arbitrary code. (CVE-2017-10111) It was discovered that a timing side-channel vulnerability existed in the DSA implementation in OpenJDK. An attacker could use this to expose sensitive information. (CVE-2017-10115) It was discovered that the LDAP implementation in OpenJDK incorrectly followed references to non-LDAP URLs. An attacker could use this to specially craft an LDAP referral URL that exposes sensitive information or bypass access restrictions. (CVE-2017-10116) It was discovered that a timing side-channel vulnerability existed in the ECDSA implementation in OpenJDK. An attacker could use this to expose sensitive information. (CVE-2017-10118) Ilya Maykov discovered that a timing side-channel vulnerability existed in the PKCS#8 implementation in OpenJDK. An attacker could use this to expose sensitive information. (CVE-2017-10135) It was discovered that the Elliptic Curve (EC) implementation in OpenJDK did not properly compute certain elliptic curve points. An attacker could use this to expose sensitive information. (CVE-2017-10176) It was discovered that OpenJDK did not properly restrict weak key sizes in some situations. An attacker could use this to specially construct an untrusted Java application or applet that could escape sandbox restrictions. (CVE-2017-10193) It was discovered that OpenJDK did not properly enforce disabled algorithm restrictions on X.509 certificate chains. An attacker could use this to expose sensitive information or escape sandbox restrictions. (CVE-2017-10198) It was discovered that OpenJDK did not properly perform access control checks when handling Web Service Definition Language (WSDL) XML documents. An attacker could use this to expose sensitive information. (CVE-2017-10243) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 17.04: openjdk-8-jre 8u131-b11-2ubuntu1.17.04.3 openjdk-8-jre-headless 8u131-b11-2ubuntu1.17.04.3 openjdk-8-jre-zero 8u131-b11-2ubuntu1.17.04.3 Ubuntu 16.04 LTS: openjdk-8-jre 8u131-b11-2ubuntu1.16.04.3 openjdk-8-jre-headless 8u131-b11-2ubuntu1.16.04.3 openjdk-8-jre-jamvm 8u131-b11-2ubuntu1.16.04.3 openjdk-8-jre-zero 8u131-b11-2ubuntu1.16.04.3 This update uses a new upstream release, which includes additional bug fixes.
