CVE-2025-11579

Description

A memory exhaustion flaw has been discovered in the golang Rar Decode library (github.com/nwaples/rardecode). Affected versions did not limit the size of an archive and so an attacker could provide a crafted archive to a tool or service built on Rar decode which might consume more memory than available. This would lead to a program crash.

Mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)

CWE-789

Availability

Technical Impact: DoS: Resource Consumption (Memory)

Not controlling memory allocation can result in a request for too much system memory, possibly leading to a crash of the application due to out-of-memory conditions, or the consumption of a large amount of memory on the system.
