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.
