Description Preview
An out-of-bounds read vulnerability (CWE-125) exists in the RS-274X aperture macro outline primitive functionality of Gerbv 2.7.0, development version (commit b5f1eacd), and the forked version (commit d7f42a9a). When processing a specially-crafted Gerber file, the application can access memory outside of allocated buffers, potentially leading to information disclosure. This vulnerability can be triggered when a user opens a malicious Gerber file provided by an attacker.
Overview
Gerbv is an open-source Gerber file viewer commonly used in PCB design workflows. The vulnerability affects the component that processes RS-274X aperture macro outline primitives within Gerber files. When parsing malformed Gerber files containing specially crafted aperture macro outline primitives, the application reads beyond the bounds of allocated memory. This can lead to information leakage from adjacent memory, potentially exposing sensitive information. The vulnerability impacts both the main Gerbv 2.7.0 release and development versions, as well as a forked version of the software.
Remediation
Users should take the following steps to mitigate this vulnerability:
- Update to a patched version of Gerbv if available
- Exercise caution when opening Gerber files from untrusted sources
- Consider using alternative Gerber viewers until a patch is available
- Implement network security controls to prevent the delivery of malicious Gerber files
- Monitor for unusual behavior when processing Gerber files
Developers working with the affected codebases should:
- Implement proper bounds checking in the RS-274X aperture macro outline primitive handling code
- Validate all input parameters before memory access operations
- Consider implementing additional input sanitization for Gerber files
