CVE-2020-8093
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 vulnerability in the AntivirusforMac binary as used in Bitdefender Antivirus for Mac allows an attacker to inject a library using DYLD environment variable to cause third-party code execution
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 AntivirusforMac binary in Bitdefender Antivirus for Mac is vulnerable to library injection via DYLD environment variables. An attacker with local access can manipulate DYLD_INSERT_LIBRARIES or similar DYLD variables to load arbitrary malicious libraries into the context of the antivirus process, achieving code execution with the privileges of the antivirus software.

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.
-
Identify Bitdefender Antivirus for Mac installationLocate the AntivirusforMac binary. Common paths include /Applications/Bitdefender Antivirus for Mac.app/Contents/MacOS/AntivirusforMac or check via 'ls /Applications/ | grep -i bitdefender'Affected if The application is not installed or the binary cannot be found, the vulnerability does not apply
-
Determine installed versionRun 'defaults read /Applications/Bitdefender\ Antivirus\ for\ Mac.app/Contents/Info CFBundleShortVersionString' or right-click the app in Finder > Get Info to view the versionAffected if The version number returned is less than 8.0.0 (for example, 7.x.x, 6.x.x, etc.)
-
Verify the vulnerable binary existsConfirm AntivirusforMac binary is present in the application bundle at /Applications/Bitdefender Antivirus for Mac.app/Contents/MacOS/AntivirusforMacAffected if The binary exists and the version from step 2 is below 8.0.0, the environment is affected
If Bitdefender Antivirus for Mac is installed and the version is below 8.0.0, the environment is vulnerable to DYLD library injection attacks.

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 data8.0.0
The vendor should patch the application to explicitly clear or sanitize DYLD environment variables before spawning child processes or loading libraries, following macOS secure coding best practices. Users should update to the patched version of Bitdefender Antivirus for Mac.
