Technical Summary
The java-1.8.0-openjdk packages for Red Hat Enterprise Linux 7 contain four security vulnerabilities: CVE-2024-21011 (long exception message leading to crash), CVE-2024-21068 (integer overflow in C1 compiler address generation), CVE-2024-21085 (Pack200 excessive memory allocation), and CVE-2024-21094 (C2 compilation failure due to exceeded _node_regs array). These issues affect the OpenJDK 8 Java Runtime Environment and Software Development Kit. Red Hat has issued a security advisory (RHSA-2024:1817) providing updated packages to address these vulnerabilities. The advisory rates the impact as moderate and instructs users to apply the update and restart all OpenJDK Java instances for the fixes to take effect.
Potential Impact
The vulnerabilities may cause application crashes, excessive memory usage, or compilation failures in Java applications running on affected versions of OpenJDK 8. These issues could potentially disrupt normal operation of Java-based software but are rated as moderate in severity by Red Hat. There are no known exploits in the wild at this time.
Mitigation Recommendations
Red Hat has released updated java-1.8.0-openjdk packages that address these vulnerabilities. Users should apply the available security update for Red Hat Enterprise Linux 7 as described in advisory RHSA-2024:1817. After applying the update, all running OpenJDK Java instances must be restarted to ensure the fixes take effect. No additional mitigation steps are required beyond applying the official update and restarting affected services.
