Null Pointer Dereference in libvips EXIF Decoder

Publication date: 2026-07-20

Last updated on: 2026-07-20

Assigner: GitHub, Inc.

Description
libvips is a fast image processing library with low memory needs. The EXIF decoder within libvips versions before and including 8.18.1 was not verifying the range of EXIF tag groups before passing data to libexif, leading to a possible null pointer dereference and crash. This has been patched in version 8.18.2.

Executive Summary

CVE-2026-35590 is a vulnerability in libvips versions before 8.18.2 where the EXIF decoder fails to validate the range of EXIF tag groups before passing data to libexif. This can cause a null pointer dereference and crash the application.

Detection Guidance

To detect this vulnerability, check the installed version of libvips on your system. Run the command 'vips --version' or 'dpkg -l libvips' on Debian-based systems or 'rpm -qa | grep libvips' on RPM-based systems. If the version is 8.18.1 or earlier, the system is vulnerable.

Impact Analysis

This vulnerability can cause the libvips application to crash due to a null pointer dereference when processing malformed EXIF data. It requires local access and low privileges but has low attack complexity.

Compliance Impact

This vulnerability primarily impacts system availability by causing crashes due to null pointer dereferences in the EXIF decoder. It does not directly involve data breaches or unauthorized access, which are key concerns for GDPR or HIPAA compliance. However, repeated crashes could disrupt services handling sensitive data, potentially leading to secondary compliance issues if critical systems fail.

Mitigation Strategies

Upgrade libvips to version 8.18.2 or later immediately. On Debian/Ubuntu, use 'sudo apt-get update && sudo apt-get install --only-upgrade libvips'. On RHEL/CentOS, use 'sudo yum update libvips'. Verify the upgrade with the version command.
