USN-3747-1: OpenJDK 10 vulnerabilities
21 August 2018
Several security issues were fixed in OpenJDK 10.
Releases
Packages
- openjdk-lts - Java runtime based on OpenJDK (debugging symbols)
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
-
openjdk-11-jre
-
10.0.2+13-1ubuntu0.18.04.1
-
openjdk-11-jre-headless
-
10.0.2+13-1ubuntu0.18.04.1
-
openjdk-11-jre-zero
-
10.0.2+13-1ubuntu0.18.04.1
This update uses a new upstream release, which includes additional bug
