Hi, The following vulnerability was published for libraw. CVE-2026-88387[0]: | LibRaw 0.22.0 contains an incorrect numeric conversion vulnerability | in LibRaw::parse_tiff_ifd() when processing TIFF tag 0x00fe | (NewSubfileType). A specially crafted RAW, TIFF, or DNG file can | supply an attacker-controlled NewSubfileType value outside the range | of a signed int. The parser converts this value and narrows it to | int without performing range validation. This out-of-range | conversion triggers undefined behavior, resulting in process | termination and denial of service. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
