CVE-2007-0557
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 · uneditedrMake before 1.0.4 drops root privileges in a way that retains the original supplemental groups, which might allow attackers to gain privileges via a crafted recipe file, a different vulnerability than CVE-2007-0536.
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 · moderate confidencerMake before version 1.0.4 contains a privilege escalation flaw where root privileges are dropped but original supplemental groups are retained. When a crafted recipe file is processed, these retained group memberships can be exploited to gain elevated privileges beyond what the dropped user should have.

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.
-
Verify rMake is installedCheck for the presence of rMake on the system using package manager queries or by searching for rMake binaries in standard locationsAffected if rMake is installed on the system
-
Determine installed rMake versionQuery the installed rMake version using commands such as 'rmake --version', 'rpm -q rmake', or checking installed package metadataAffected if The installed version is 1.0.3 or earlier
-
Identify recipe file processing usageCheck if rMake recipe files are being executed or if the recipe processing feature is actively used in the environmentAffected if Recipe files are processed by rMake and the system permits running recipes from untrusted sources
-
Inspect user privilege configurationReview how rMake handles privilege dropping by examining configuration files, startup scripts, or process behavior when executed with elevated privilegesAffected if rMake is configured to run with root privileges and then drop privileges while retaining supplemental group memberships
-
Check for untrusted recipe filesScan the environment for recipe files that may come from untrusted sources or have been modified by non-privileged usersAffected if Untrusted or user-supplied recipe files exist in directories accessible to rMake
The environment is affected if rMake version 1.0.3 or earlier is installed and processes recipe files while dropping root privileges but retaining supplemental group memberships.

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 dataUpgrade rMake to version 1.0.4 or later, which properly clears supplemental group memberships when dropping root privileges. Verify no untrusted recipe files exist in the environment.
