fix: upgrade packages in agent container to mitigate CVE-2023-44487#760
Conversation
Add an apt-get upgrade step after the main package installation in the agent Dockerfile. This ensures all base image packages (including Node.js) receive the latest security patches, addressing the HTTP/2 Rapid Reset Attack vulnerability (CVE-2023-44487) and other known CVEs. While this CVE primarily affects HTTP/2 server implementations and the agent container acts as a client, upgrading packages is the most robust defense-in-depth approach.

Pull request overview
This PR adds an apt-get upgrade -y step to the agent container Dockerfile to mitigate CVE-2023-44487 (HTTP/2 Rapid Reset Attack) and other security vulnerabilities by upgrading all installed packages to their latest available versions.
Changes:
- Adds package upgrade step after initial package installation in agent Dockerfile to pick up security patches
- Includes explanatory comment documenting the security rationale (CVE-2023-44487)
Comments suppressed due to low confidence (2)

- Consider the tradeoffs of using
apt-get upgradeversus the existingno-cache: trueapproach in the release workflow. The release.yml workflow (line 104) already usesno-cache: truespecifically to ensure security-critical packages are freshly installed. Addingapt-get upgradeprovides an additional layer but may introduce reproducibility concerns since package versions can change between builds even with the same Dockerfile. Consider whether both approaches are needed, or if updating the base image version periodically would be more predictable. Also note that CVE-2023-44487 is from 2023 and should already be patched in Ubuntu 22.04 repositories - if Trivy is still reporting it, investigate whether it's a false positive or if the base image needs updating.

RUN apt-get update && apt-get upgrade -y && rm -rf /var/lib/apt/lists/*
containers/agent/Dockerfile:38
- The
--no-install-recommendsflag is missing from the upgrade command, which is inconsistent with the existing package installation patterns in this Dockerfile (lines 16, 75) and the squid Dockerfile. Whileapt-get upgradedoesn't typically install new recommended packages, using the flag explicitly maintains consistency with the codebase's minimalist container philosophy and makes the intent clear.

The Dockerfile.minimal (used for chroot mode) should also receive the same apt-get upgrade step for consistency. While chroot mode relies more on host binaries, the minimal image still includes iptables, iproute2, and git packages that could have security vulnerabilities. Consider adding the same upgrade step after the package installation in Dockerfile.minimal (after line 19).
