ALSA-2025:10873: java-21-openjdk security update (Important)
Hi,
You are receiving an AlmaLinux Security update email because you subscribed to receive errata notifications from AlmaLinux.
AlmaLinux: 8
Type: Security
Severity: Important
Release date: 2025-07-30
Summary:
The OpenJDK 21 packages provide the OpenJDK 21 Java Runtime Environment and the OpenJDK 21 Java Software Development Kit.
Security Fix(es):
* JDK: Better Glyph drawing (CVE-2025-30749)
* JDK: Enhance TLS protocol support (CVE-2025-30754)
* JDK: Improve HTTP client header handling (CVE-2025-50059)
* JDK: Better Glyph drawing redux (CVE-2025-50106)
Bug Fix(es):
* In AlmaLinuxand AlmaLinux systems, the default graphical display system is Wayland. The use of Wayland in these systems causes a failure in the traditional X11 method that java.awt.Robot uses to take a screen capture, producing a blank image. With this update, the RPM now recommends installing the PipeWire package, which the JDK can use to take screen captures in Wayland systems (AlmaLinux-102683, AlmaLinux-102684, AlmaLinux-102685)
* On NUMA systems, the operating system can choose to migrate a task from one NUMA node to another. In the G1 garbage collector, G1AllocRegion objects are associated with NUMA nodes. The G1Allocator code assumes that obtaining the G1AllocRegion object for the current thread is sufficient, but OS scheduling can lead to arbitrary changes in the NUMA-to-thread association. This can cause crashes when the G1AllocRegion being used changes mid-operation. This update resolves this issue by always using the same NUMA node and associated G1AllocRegion object throughout an operation. (AlmaLinux-90307, AlmaLinux-90308, AlmaLinux-90311)
