Ubuntu has rolled out critical security updates for several key software components, including the Linux kernel, GNU binutils, Node.js, and LibXML2. These updates address various vulnerabilities that could compromise system security across its supported versions.
Linux Kernel Update:
The Linux kernel for AWS systems (version linux-aws-5.15) has been updated to address multiple vulnerabilities, including an out-of-bounds write issue in the watch_queue event notification subsystem that could lead to denial of service or privilege escalation (CVE-2022-0995). Other vulnerabilities affecting subsystems like iSCSI, network drivers, and file systems were also patched. Users are advised to update and reboot their systems due to significant changes in the kernel ABI.
GNU Binutils Update:
Updates for GNU binutils have been released for Ubuntu 16.04 LTS and 18.04 LTS, fixing issues that could lead to crashes or arbitrary code execution due to improper handling of certain inputs (CVE-2025-0840, CVE-2025-1153, CVE-2025-1176). A standard system update will apply these changes.
Node.js Update:
Node.js received an update addressing a vulnerability that could cause crashes when subjected to specially crafted network traffic. This issue was linked to the Apache Traffic Server's handling of HTTP/2 protocol (CVE-2023-44487). Update instructions for various Ubuntu versions are provided, and users must restart Node.js post-update.
LibXML2 Update:
LibXML2 has also been patched to rectify vulnerabilities that could result in denial of service attacks due to improper memory handling and Python bindings (CVE-2025-32414, CVE-2025-32415). Users on Ubuntu 16.04 LTS and 18.04 LTS are encouraged to update their systems through standard methods.
Overall, these updates are crucial for maintaining the security integrity of Ubuntu systems, and users are encouraged to regularly check for and apply updates to safeguard their devices.
