USN-3747-2: OpenJDK 10 regression
12 September 2018
USN-3747-1 introduced a regression in OpenJDK 10.
- openjdk-lts - Open Source Java implementation
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)
The problem can be corrected by updating your system to the following package versions:
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.
