GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

RHSA-2026:63357

Vulnerability from csaf_redhat - Published: 2026-09-03 21:01 - Updated: 2026-09-06 18:04
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.

A flaw was found in brace-expansion. An attacker can exploit a vulnerability in the `expand()` function by providing a specially crafted string. This string, containing consecutive non-expanding brace groups, can trigger exponential-time complexity, leading to significant CPU consumption and event-loop blocking. This can result in a Denial of Service (DoS) for the affected system.

Vendor Fix fix
Workaround
Threats
Impact Important

A flaw was found in the brace-expansion library. The `expand()` function does not apply `maxLength` when constructing comma-alternative intermediate arrays or padded sequences, allowing attacker-controlled input to exhaust memory or block the event loop, resulting in a denial of service. This issue is due to an incomplete mitigation of CVE-2026-14257.

CWE-770 - Allocation of Resources Without Limits or Throttling

Threats
Impact Important

A flaw was found in the `ip-address` library. This library incorrectly interprets IPv4 address octets with leading zeros as decimal, while standard network parsers interpret them as octal. This inconsistency can cause applications to misclassify network targets, allowing a remote attacker to bypass security measures like Server-Side Request Forgery (SSRF) filters and potentially gain unauthorized access to internal systems.

CWE-1389 - Incorrect Parsing of Numbers with Different Radices
