Overview
CVE-2025-43961 is a security vulnerability discovered in LibRaw versions before 0.21.4, affecting the metadata/tiff.cpp component. The vulnerability was disclosed on April 20, 2025, and involves an out-of-bounds read vulnerability in the Fujifilm 0xf00c tag parser (NVD, RedHat).
Technical details
The vulnerability is classified as CWE-125 (Out-of-bounds Read) with a CVSS 3.1 Base Score of 2.9 (LOW), and vector string CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L. This indicates a local attack vector with high attack complexity, requiring no privileges or user interaction, and potentially resulting in low availability impact (NVD).
