CVE-2026-88387: n/a
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.
AI Analysis
Technical Summary
The vulnerability in LibRaw 0.22.0 arises from improper numeric conversion in the parse_tiff_ifd() function when processing the TIFF tag 0x00fe (NewSubfileType). The parser converts an attacker-controlled value to a signed int without range checking, which can cause undefined behavior and crash the process. This can be exploited by supplying a specially crafted RAW, TIFF, or DNG file with a NewSubfileType value outside the valid signed int range, resulting in denial of service.
Potential Impact
Successful exploitation causes process termination due to undefined behavior triggered by out-of-range numeric conversion. This results in denial of service to the application using LibRaw 0.22.0 when parsing maliciously crafted image files.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid processing untrusted RAW, TIFF, or DNG files with LibRaw 0.22.0.
