CVE-2024-29903

Description

A flaw was found in the Cosign package where maliciously crafted software artifacts can trigger uncontrolled resource consumption by allocating too much memory and starving out the system. A successful attack may result in a denial of service of the machine running Cosign, impacting availability.

Statement

This vulnerability results only in a Denial-of-Service (DoS) against the Cosign service. Additionally, exploitation requires that the service is configured to accept artifacts from untrusted sources. Consequently, Red Hat's assessment indicates the security impact of this vulnerability is Moderate.

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).

Understanding the Weakness (CWE)

CWE-770

Availability

Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)

When allocating resources without limits, an attacker could prevent other systems, applications, or processes from accessing the same type of resource. It can be easy for an attacker to consume many resources by rapidly making many requests or causing larger resources to be used than is needed.
