USN-4083-1: OpenJDK 11 vulnerabilities openjdk-lts vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 19.04 Ubuntu 18.04 LTS Summary Several security issues were fixed in OpenJDK 11. Software Description openjdk-lts – Open Source Java implementation Details It was discovered that OpenJDK did not sufficiently validate serial streams before deserializing suppressed exceptions in some situations. An attacker could use this to specially craft an object that, when deserialized, would cause a denial of service. (CVE-2019-2762) It was discovered that in some situations OpenJDK did not properly bound the amount of memory allocated during object deserialization. An attacker could use this to specially craft an object that, when deserialized, would cause a denial of service (excessive memory consumption). (CVE-2019-2769) It was discovered that OpenJDK did not properly restrict privileges in certain situations. An attacker could use this to [ more… ]
