Red Hat Security Advisory: Technical preview of the satellite/iop-vmaas-rhel9 container image

🔗 CVE IDs covered (1)

📋 Description

🎯 Affected products2

• Red Hat Satellite 6.18
• registry.redhat.io/satellite/iop-vmaas-rhel9@sha256:16cceb5785ba30e59c87d5a0cca44e4cbe73aae985d6e65c39b0c49d264f3a69_amd64 as a component of Red Hat Satellite 6.18

✅ Remediation

For Red Hat Lightspeed in Satellite installation see the Red Hat Satellite documentation. Workaround: To mitigate this vulnerability, upgrade to GitPython version 3.1.59 or later, which correctly includes `--separate-git-dir` in the unsafe options denylist. If upgrading is not immediately possible, ensure that the `separate_git_dir` parameter is never populated from untrusted or user-controlled sources. Applications should validate and sanitize any input before passing it to GitPython cloning methods, or avoid exposing the `separate_git_dir` parameter to external callers entirely.
