Kimageformats: Index-out-of-bounds in LibRaw::apply_tiff
OSS-Fuzz report: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=55722 ``` Crash type: Index-out-of-bounds Crash state: LibRaw::apply_tiff LibRaw::parse_jpeg LibRaw::identify ```
AI Analysis
Technical Summary
The vulnerability is an index-out-of-bounds error occurring in the LibRaw::apply_tiff function within the kimageformats project. This flaw was discovered via OSS-Fuzz and results in a crash state involving LibRaw functions responsible for parsing JPEG and identifying image formats. The issue likely arises from improper bounds checking when handling TIFF image data, leading to potential memory safety violations.
Potential Impact
The vulnerability causes a crash due to out-of-bounds memory access during TIFF image processing. While the direct impact is a denial of service via application crash, no information is provided about further exploitation such as code execution or data corruption. There are no known exploits in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory or OSS-Fuzz issue tracker for current remediation guidance. Until a fix is available, avoid processing untrusted TIFF images with the affected kimageformats versions.
