fix: upgrade gpgv in squid container to address CVE-2025-68973 #757
Conversation
The squid container's base image includes gpgv 2.4.4-2ubuntu17.3 which is vulnerable to an information disclosure and potential arbitrary code execution via out-of-bounds write. Adding an explicit upgrade step ensures gpgv is updated to the patched version (2.4.4-2ubuntu17.4+). Co-Authored-By: Claude Opus 4.6 <[email protected]>

Pull request overview
This pull request adds an explicit package upgrade for gpgv in the squid container to address CVE-2025-68973, which allegedly affects information disclosure and arbitrary code execution. The change inserts an apt-get install -y --only-upgrade gpgv command between the apt-get update and the main package installation in the squid Dockerfile.
Changes:
- Adds explicit upgrade of
gpgvpackage in squid container Dockerfile to pull version2.4.4-2ubuntu17.4+

- The upgrade command uses
--only-upgrade gpgvwhich will silently succeed even if gpgv is not currently installed in the base image or if the package name is incorrect. Consider adding error handling:
apt-get install -y --only-upgrade gpgv || \
(echo "ERROR: Failed to upgrade gpgv" && exit 1)Or verify the package is actually installed:
dpkg -l gpgv && apt-get install -y --only-upgrade gpgvThis ensures the upgrade actually happens rather than silently failing if the base image doesn't include gpgv.
apt-get install -y --only-upgrade gpgv && \

CVE-2025-68973 does not appear to exist. As of January 2025 (my knowledge cutoff), CVE identifiers are only assigned up through CVE-2024-XXXXX. CVE-2025-68973 is either fabricated or uses an incorrect identifier format. Additionally, gpgv (GnuPG signature verification tool) version 2.4.4 would need to be confirmed as actually vulnerable to any real CVE.
Before applying this change:
- Verify the CVE identifier is correct and corresponds to a real vulnerability
- Confirm that gpgv in ubuntu/squid:latest is actually affected
- Check if there's an official security advisory from Ubuntu or the GnuPG project
- Verify that the upgrade actually addresses the vulnerability
If this CVE is fictional or the vulnerability doesn't affect this container, this change adds unnecessary complexity and potential breaking changes without security benefit.

The PR description mentions verifying the gpgv version is ">= 2.4.4-2ubuntu17.4", but there's no test coverage to verify this version requirement. Since this is a security fix, consider adding:
- A build-time verification that checks the gpgv version after the upgrade
- Integration test that validates the package version in the built container
- Documentation of the specific vulnerability and version requirement
This would prevent regression if the base image changes or the package repository no longer provides the patched version.
This issue also appears on line 8 of the same file.
See below for a potential fix:
# Retry logic handles transient 404s when Ubuntu archive supersedes package versions mid-build
# Security hardening: ensure gpgv is at or above the required patched version to avoid regressions

This change deviates from the codebase's existing approach to container security. Looking at the agent Dockerfile (containers/agent/Dockerfile), package installations don't include explicit security updates for individual packages. The codebase relies on the base images (ubuntu/squid:latest, ubuntu:22.04) to provide security-patched packages.
If security-critical package updates are needed, consider:
- Documenting this as a new pattern in the codebase
- Applying the same approach to the agent container if needed
- Creating a process for monitoring and updating both containers for security issues
Alternatively, if ubuntu/squid:latest doesn't provide timely security updates, consider:
- Switching to a more actively maintained base image
- Building from a minimal ubuntu base and installing squid packages explicitly
- Documenting why this container requires special security treatment
