**Name of the Vulnerable Software and Affected Versions** netpbm versions prior to 10.25 **Description** The issue arises when using the -trans option in pnmtopng for converting Portable Anymap (PNM) images to Portable Network Graphics (PNG). It uses uninitialized size and index variables, which could potentially allow attackers to execute arbitrary code by modifying the stack. **Recommendations** For versions prior to 10.25, update to version 10.25 or later to resolve the issue.
