3. 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: improper connection handling during TLS handshake (8294474)
(CVE-2023-21930)

* OpenJDK: Swing HTML parsing issue (8296832) (CVE-2023-21939)

* OpenJDK: incorrect enqueue of references in garbage collector (8298191)
(CVE-2023-21954)

* OpenJDK: certificate validation issue in TLS session negotiation
(8298310) (CVE-2023-21967)

* OpenJDK: missing string checks for NULL characters (8296622)
(CVE-2023-21937)

* OpenJDK: incorrect handling of NULL characters in ProcessBuilder
(8295304) (CVE-2023-21938)

* OpenJDK: missing check for slash characters in URI-to-path conversion
(8298667) (CVE-2023-21968)

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):

* Native code within the OpenJDK code base attempted to call close() on a
file descriptor repeatedly if it returned the error code, EINTR. However,
the close() native call is not restartable and this caused the virtual
machine to crash. The close() call is now only made once. (RHBZ#2159458)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

All running instances of OpenJDK Java must be restarted for this update to
take effect.

5. Bugs fixed (https://bugzilla.redhat.com/):

2159458 - Do not restart close if errno is EINTR [rhel-7.9.z]
2187435 - CVE-2023-21930 OpenJDK: improper connection handling during TLS handshake (8294474)
