Software Description: - openjdk-lts: Open Source Java implementation - openjdk-8: Open Source Java implementation Details: It was discovered that the BigDecimal implementation in OpenJDK performed excessive computation when given certain values. An attacker could use this to cause a denial of service (excessive CPU usage). (CVE-2019-2602) Corwin de Boor and Robert Xiao discovered that the RMI registry implementation in OpenJDK did not properly select the correct skeleton class in some situations. An attacker could use this to possibly escape Java sandbox restrictions. (CVE-2019-2684) Mateusz Jurczyk discovered a vulnerability in the 2D component of OpenJDK. An attacker could use this to possibly escape Java sandbox restrictions. This issue only affected OpenJDK 8 in Ubuntu 16.04 LTS. (CVE-2019-2697) Mateusz Jurczyk discovered a vulnerability in the font layout engine of OpenJDK's 2D component. An attacker could use this to possibly escape Java sandbox restrictions. This issue only affected OpenJDK 8 in Ubuntu 16.04 LTS. (CVE-2019-2698) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 19.04: Ubuntu 18.10: Ubuntu 18.04 LTS: Ubuntu 16.04 LTS: 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. References: Package Information: |
