Synopsis
Moderate: java-1.8.0-openjdk security and bug fix update
Type/Severity
Security Advisory: Moderate
Topic
An update for java-1.8.0-openjdk is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Description
The java-1.8.0-openjdk packages provide the OpenJDK 8 Java Runtime Environment and the OpenJDK 8 Java Software Development Kit.
Security Fix(es):
- OpenJDK: insufficient index validation in PatternSyntaxException getMessage() (Concurrency, 8199547) (CVE-2018-2952)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
Note: If the web browser plug-in provided by the icedtea-web package was installed, the issues exposed via Java applets could have been exploited without user interaction if a user visited a malicious website.
Bug Fix(es):
- This update applies changes from OpenJDK upstream version 8u172, which provides a number of bug fixes over the previous version, 8u171. (BZ#1588364)
- OpenJDK was recently updated to support reading the system certificate authority database (cacerts) directly. As an unintended consequence, this removed the ability to read certificates from the user-provided jssecacerts file. With this update, that ability is restored by reading from that file first, if available. (BZ#1593737)
Solution
