A vulnerability in the vipsload operation of libvips versions up to and including 8.18.0 can cause incorrect image dimension calculations, resulting in an integer overflow and a heap-based buffer overflow. This flaw has been addressed in version 8.18.1.
AI Analysis
Technical Summary
The vipsload operation in libvips, a fast image processing library, incorrectly determines image dimensions in versions before and including 8.18.0. This miscalculation leads to an integer overflow, which subsequently causes a heap-based buffer overflow. The vulnerability is fixed in version 8.18.1.
Potential Impact
Successful exploitation could allow an attacker with local privileges to cause a heap-based buffer overflow, potentially leading to arbitrary code execution or denial of service. The CVSS score of 7.8 indicates high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Upgrade libvips to version 8.18.1 or later, where this vulnerability has been patched. No other mitigations are specified.
