Unfortunately, that update introduced a regression around accessibility
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)");
