Security Bulletin: Vulnerability in Google Guava affects IBM Cloud Pak System (CVE-2018-10237)

Summary

There is a potential denial of service with the Google Guava library that is used in IBM Cloud Pak System.

Vulnerability Details

CVEID:CVE-2018-10237
**DESCRIPTION:**Unbounded memory allocation in Google Guava 11.0 through 24.x before 24.1.1 allows remote attackers to conduct denial of service attacks against servers that depend on this library and deserialize attacker-provided data, because the AtomicDoubleArray class (when serialized with Java serialization) and the CompoundOrdering class (when serialized with GWT serialization) perform eager allocation without appropriate checks on what a client has sent and whether the data size is reasonable.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/142508 for the current score.
