RHSA-2023:0192 - Security Advisory

Topic

An update for java-17-openjdk is now available for Red Hat Enterprise Linux 8.

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-17-openjdk packages provide the OpenJDK 17 Java Runtime Environment and the OpenJDK 17 Java Software Development Kit.

Security Fix(es):

• OpenJDK: handshake DoS attack against DTLS connections (JSSE, 8287411) (CVE-2023-21835)
• OpenJDK: soundbank URL remote loading (Sound, 8293742) (CVE-2023-21843)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

• In FIPS mode, the use of a SQLite database provided by NSS was assumed, which was opened in read-only mode and with no PIN expected. This prevented the use of other databases or setting a PIN on the NSS database. This update allows more control over database use using two new properties - fips.nssdb.path and fips.nssdb.pin - which can be configured permanently in the java.security file or temporarily via command-line arguments to the Java virtual machine (RHBZ#2147473)
• Prepare for the next quarterly OpenJDK upstream release (2023-01, 17.0.6) [rhel-8] (BZ#2153010)
