CVE-2022-31782
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 · uneditedftbench.c in FreeType Demo Programs through 2.12.1 has a heap-based buffer overflow.
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 confidenceA heap-based buffer overflow vulnerability exists in ftbench.c, a benchmark utility included in FreeType Demo Programs through version 2.12.1. The vulnerability allows an attacker to overwrite heap memory by providing specially crafted input to the ftbench tool, potentially leading to arbitrary code execution or denial of service.

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.
-
Locate the ftbench executableSearch for the ftbench binary on the system using 'which ftbench' or 'find /usr -name ftbench 2>/dev/null'. Also check common bin directories like /usr/bin, /usr/local/bin, or installation directories used for FreeType demo programs.Affected if The ftbench executable is found on the system, indicating the FreeType Demo Programs are installed.
-
Determine the FreeType Demo Programs versionRun 'ftbench -v' or 'ftbench --version' if available. Alternatively, check the package manager for installed freetype-demo-packages using commands like 'dpkg -l | grep freetype' (Debian/Ubuntu) or 'rpm -qa | grep freetype' (RHEL/CentOS).Affected if The version returned is 2.12.1 or earlier, or the version cannot be determined but the demo programs are present.
-
Verify the ftbench tool is accessibleCheck file permissions on the ftbench binary using 'ls -la' to see if it is executable by users. Confirm the binary exists in a location accessible to standard users.Affected if The ftbench binary is executable by users who could run it with malicious input.
-
Identify if ftbench is in use or exposedReview any scripts, cron jobs, or applications that invoke ftbench. Check if ftbench is accessible via web-facing paths or shared directories where untrusted users could supply crafted input.Affected if ftbench is accessible to untrusted users or processes that could provide specially crafted input.
A user is affected if the FreeType Demo Programs (specifically ftbench) version 2.12.1 or earlier is installed and accessible to users who could run it with crafted input.

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.
dbcve · scopedUpdate FreeType Demo Programs to version 2.12.1 or later when patches become available. If using ftbench in production environments, remove or restrict access to demo programs until the fix is applied.
FreeType 2.12.2 or later stable release
- 1. Identify all systems running FreeType Demo Programs version 2.12.1 or earlier
- 2. Download the latest stable release of FreeType from the official repository or distribution package manager
- 3. Replace the vulnerable ftbench.c utility with the updated version from the new release
- 4. Rebuild and redeploy the demo programs if compiled from source
- 5. Verify the installation by checking the FreeType library version (freetype-config --version)
