CVE-2026-3381
Description
A flaw was found in Compress::Raw::Zlib. This component bundles an outdated version of the zlib compression library, which contains known security vulnerabilities. An attacker could potentially exploit these underlying zlib vulnerabilities through Compress::Raw::Zlib, leading to unspecified security impacts.
Statement
This has been rated as moderate as the older version of zlib only has two known flaws, and one of them is a bufferoverflow that is in the contrib directory, and so are not part of zlib.
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.

Technical Impact: Reduce Maintainability; Varies by Context
Relying on unmaintained components makes it difficult or impossible to fix significant bugs and vulnerabilities, can render code obsolete, and undermine security by complicating maintenance and increasing the risk of new vulnerabilities.
