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.
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).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
