Alpine: multiple openjdk21 packages: security update to 21.0.13.0.3_p1-r0

critical Tenable Self-Hosted Container Security Plugin ID 478110

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- An issue was discovered in GStreamer gst-plugins-good before 1.28.2. When parsing MP4 audio tracks, the
isomp4 plugin's qtdemux_audio_caps function does not sufficiently validate atom data before performing
division operations, leading to denial of service due to integer division by zero. (CVE-2026-46470)

- Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
Oracle Java SE (component: JSSE). Supported versions that are affected are Oracle Java SE: 8u511-b32,
8u511-perf-b32, 11.0.33.0.2, 17.0.21.0.2, 21.0.13.0.2, 25.0.5.0.2, 27.0.1.0.2; Oracle GraalVM for JDK:
17.0.21.0.2 and 21.0.13.0.2; Oracle GraalVM Enterprise Edition: 21.3.20.0.2. Easily exploitable
vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise
Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Successful attacks of this
vulnerability can result in unauthorized creation, deletion or modification access to critical data or all
Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition accessible data as well as
unauthorized access to critical data or complete access to all Oracle Java SE, Oracle GraalVM for JDK,
Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability can be exploited by using APIs
in the specified Component, e.g., through a web service which supplies data to the APIs. This
vulnerability also applies to Java deployments, typically in clients running sandboxed Java Web Start
applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the
internet) and rely on the Java sandbox for security. (CVE-2026-114820)

- A flaw was found in libxml2. This vulnerability occurs when the library processes a specially crafted XML
Schema Definition (XSD) validated document that includes an internal entity reference. An attacker could
exploit this by providing a malicious document, leading to a type confusion error that causes the
application to crash. This results in a denial of service (DoS), making the affected system or application
unavailable. (CVE-2026-6732)

- Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
Oracle Java SE (component: Security). Supported versions that are affected are Oracle Java SE: 8u503,
8u503-perf, 11.0.32.1, 17.0.20.1, 21.0.12.1, 25.0.4.1, 27; Oracle GraalVM for JDK: 17.0.20.1 and
21.0.12.1; Oracle GraalVM Enterprise Edition: 21.3.19.1.1. Difficult to exploit vulnerability allows
unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle
GraalVM for JDK, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in
unauthorized creation, deletion or modification access to critical data or all Oracle Java SE, Oracle
GraalVM for JDK, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability can be
exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the
APIs. This vulnerability also applies to Java deployments, typically in clients running sandboxed Java Web
Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from
the internet) and rely on the Java sandbox for security. (CVE-2026-83374)
