RHSA-2023:0191 - Security Advisory

Topic

An update for java-17-openjdk is now available for Red Hat Enterprise Linux 8.4 Extended Update Support.

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 (BZ#2147475)
• With previous Red Hat builds of OpenJDK 17, Mac key generation and import

would fail due to the lack of the CKA_SIGN attribute on the key. This attribute is now added as part of the NSS FIPS configuration. (BZ#2108191)

• NSS has offered a SQLite SecMod database for some time, and this has been available in RHEL as far back as RHEL 6. With newer NSS versions removing the Berkeley DB one, this update switches the FIPS support backed by NSS to use the SQLite backend (BZ#2023536)
• [rpminspect] Disable Java bytecode checks [java-17-openjdk, rhel-8] (BZ#2109107)
• Use the NSS SQL Database in FIPS Mode [rhel-8, openjdk-17] (BZ#2147479)
