CVE-2017-9274
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 · uneditedA shell command injection in the obs-service-source_validator before 0.7 could be used to execute code as the packager when checking RPM SPEC files with specific macro constructs.
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 confidenceA shell command injection vulnerability in obs-service-source_validator before version 0.7 allows attackers to execute arbitrary code as the packager user by crafting malicious RPM SPEC files with specific macro constructs that get evaluated by the validator.

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 if obs-service-source_validator is installedCheck for the presence of the obs-service-source_validator package using your system package manager (e.g., rpm -qa | grep source_validator, dpkg -l | grep source_validator, or zypper se source_validator)Affected if The package is installed on the system
-
Determine the installed versionQuery the installed package version using the appropriate package manager command (e.g., rpm -q obs-service-source_validator or rpm -qi obs-service-source_validator)Affected if The installed version is lower than 0.7 (e.g., 0.6.x, 0.5.x, or any version < 0.7)
-
Confirm the source_validator service is in useCheck if the source_validator service is enabled or has been executed recently - look for service logs, cron jobs, or configuration files that reference source_validatorAffected if The service is enabled or has recent execution history, indicating it processes SPEC files from potentially untrusted sources
-
Inspect recent SPEC file processingReview service logs or temporary directories for recent SPEC file validations - check for any processed .spec files from external or untrusted sourcesAffected if The validator has recently processed SPEC files from sources outside your trusted codebase
You are affected if obs-service-source_validator version less than 0.7 is installed AND the service processes or can process SPEC files from untrusted sources.

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 data0.7
Upgrade obs-service-source_validator to version 0.7 or later to patch the command injection vulnerability. If immediate patching is not possible, restrict access to the source_validator service and validate all SPEC files before processing.
