August 22 2018: Initial Release - --------------------------BEGIN INCLUDED TEXT-------------------- ========================================================================== Ubuntu Security Notice USN-3747-2 September 12, 2018 openjdk-lts regression ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - - Ubuntu 18.04 LTS Summary: USN-3747-1 introduced a regression in OpenJDK 10. Software Description: - - openjdk-lts: Open Source Java implementation Details: USN-3747-1 fixed vulnerabilities in OpenJDK 10 for Ubuntu 18.04 LTS. Unfortunately, that update introduced a regression around accessability support that prevented some Java applications from starting. This update fixes the problem. We apologize for the inconvenience. Original advisory details: It was discovered that OpenJDK did not properly validate types in some situations. An attacker could use this to construct a Java class that could possibly bypass sandbox restrictions. (CVE-2018-2825, CVE-2018-2826) It was discovered that the PatternSyntaxException class in OpenJDK did not properly validate arguments passed to it. An attacker could use this to potentially construct a class that caused a denial of service (excessive memory consumption). (CVE-2018-2952) Daniel Bleichenbacher discovered a vulnerability in the Galois/Counter Mode (GCM) mode of operation for symmetric block ciphers in OpenJDK. An attacker could use this to expose sensitive information. (CVE-2018-2972) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS: openjdk-11-jdk 10.0.2+13-1ubuntu0.18.04.2 openjdk-11-jdk-headless 10.0.2+13-1ubuntu0.18.04.2 openjdk-11-jre 10.0.2+13-1ubuntu0.18.04.2 openjdk-11-jre-headless 10.0.2+13-1ubuntu0.18.04.2 openjdk-11-jre-zero 10.0.2+13-1ubuntu0.18.04.2 This update uses a new upstream release, which includes additional bug fixes. After a standard system update you need to restart any Java applications or applets to make all the necessary changes.
