Summary
Red Hat Security Advisory: General availability of the satellite/iop-remediations-rhel9 container image
Severity
Important
Notes
Topic: A new satellite/iop-remediations-rhel9 container image is now generally available in the Red Hat container registry.
Details: Red Hat Lightspeed in Satellite analyzes system health and configuration by applying predefined rules to a small set of local data, such as installed packages, running services, and configuration settings. When you install Red Hat Lightspeed in Satellite locally, you can generate Red Hat Lightspeed recommendations without sending system data to Red Hat services.

CVE-2026-42338

A flaw was found in ip-address, a JavaScript library for parsing and manipulating IPv4 and IPv6 addresses. This vulnerability allows a remote attacker to perform cross-site scripting (XSS) by providing untrusted input to the Address6 constructor. When an application renders the output of Address6.group(), Address6.link(), or the AddressError.parseMessage as HTML without proper escaping, the attacker-controlled content can be executed in the user's browser.

8.1 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N

CVE-2026-59873

A flaw was found in node-tar, a tar archive manipulation library for Node.js. This vulnerability allows a remote attacker to craft a small gzip bomb, which, when processed, can lead to the exhaustion of disk space and CPU resources. This occurs because node-tar does not enforce strict limits on the total decompressed data, the number of entries, or the decompression ratio during extraction and parsing. The primary impact is a Denial of Service (DoS), making the affected system or application unavailable.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
CWE-770 - Allocation of Resources Without Limits or Throttling

CVE-2026-59874

A flaw was found in node-tar, a tar archive manipulation library for Node.js. A remote attacker could exploit this vulnerability by providing a specially crafted tar archive with a negative entry size in its header. This malformed header causes the archive scanner to enter an infinite loop, repeatedly parsing the same header and preventing further processing. This can lead to a denial of service (DoS) condition, making the affected system or application unresponsive.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
