Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:4006-1 advisory.

Security issues fixed:

- CVE-2026-60589: OpenJDK: Improve Resource Resolving (bsc#1275777).
- CVE-2026-61308: OpenJDK: Enhance HTTP Connections (bsc#1275778).
- CVE-2026-70907: OpenJDK: Enhance TLS server (bsc#1275764).

Non security issue fixed:

- java-21-openjdk classlist depends on the CPU count of the build machine (bsc#1221224).

Changes for java-21-openjdk:

- Update to jdk-21.0.12.1+1 (August 2026 CSPU) + backport upcoming upgrade of timezone data (bsc#1275035) + Explicitly use G1 if the JVM supports it. GC ergonomics pick SerialGC on single-CPU machines. SerialGC does not support dumping of the shared heap, thus the classlist is different on a single-CPU builder.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected java-21-openjdk, java-21-openjdk-demo, java-21-openjdk-devel and / or java-21-openjdk-headless packages.
