SCA: security update for github.com/argoproj/argo-cd/v2 (GHSA-g687-f2gx-6wm8)

medium Tenable Self-Hosted Container Security Plugin ID 414929

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Argo CD is a declarative continuous deployment for Kubernetes. All versions of ArgoCD starting from v2.4
 have a bug where the ArgoCD repo-server component is vulnerable to a Denial-of-Service attack vector.
 Specifically, the said component extracts a user-controlled tar.gz file without validating the size of its
 inner files. As a result, a malicious, low-privileged user can send a malicious tar.gz file that exploits
 this vulnerability to the repo-server, thereby harming the system's functionality and availability.
 Additionally, the repo-server is susceptible to another vulnerability due to the fact that it does not
 check the extracted file permissions before attempting to delete them. Consequently, an attacker can craft
 a malicious tar.gz archive in a way that prevents the deletion of its inner files when the manifest
 generation process is completed. A patch for this vulnerability has been released in versions 2.6.15,
 2.7.14, and 2.8.3. Users are advised to upgrade. The only way to completely resolve the issue is to
 upgrade, however users unable to upgrade should configure RBAC (Role-Based Access Control) and provide
 access for configuring applications only to a limited number of administrators. These administrators
 should utilize trusted and verified Helm charts. (CVE-2023-40584)
