Details

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.
