CVE-2007-0536
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe chroot helper in rMake for rPath Linux 1 does not drop supplemental groups, which causes packages to be installed with insecure permissions and might allow local users to gain privileges.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe chroot helper in rMake for rPath Linux 1 fails to drop supplemental group memberships before installing packages within a chroot environment. This causes installed packages to retain broader group permissions than intended, potentially allowing local unprivileged users to access sensitive package files and escalate privileges.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if rMake is installedQuery the package manager or look for rMake binaries on the system (for example, run 'rpm -qa | grep rmake' or 'which rmake' if using rpm-based rPath Linux)Affected if rMake is installed on rPath Linux 1
-
Confirm the rPath Linux versionCheck the installed OS version (for example, 'cat /etc/redhat-release' or 'cat /etc/rpath-version' if such a file exists on rPath-based systems)Affected if The system is running rPath Linux version 1
-
Identify if the chroot helper is being usedReview rMake configuration files or logs to determine if chroot environments are being created and used for package installationAffected if rMake is configured to use chroot environments for package installation
-
Inspect the chroot helper privilege handlingExamine the rMake chroot helper script or configuration for how it handles group memberships during chroot operations - look for whether setgid/setgroups calls are present before package installationAffected if The chroot helper does not properly drop supplemental group memberships (no setgid/setgroups calls found before package installation)
-
Check ownership and permissions of recently installed packagesReview group ownership and permissions on package files installed within chroot environments to see if they have broader group access than intendedAffected if Installed packages in chroot show unexpected group ownership or broader group permissions than expected
The system is affected if it runs rPath Linux 1 with rMake and uses its chroot helper functionality, and the chroot helper script fails to drop supplemental group memberships before package installation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataConfigure the rMake chroot helper to properly drop supplemental group memberships using appropriate privilege separation mechanisms (setgid/setgroups) before package installation, or upgrade to a patched version of rMake that addresses this issue.
