Doc Text:
A flaw was found in libvips, an image processing library. The `tiffload` operation, which handles loading TIFF images, could incorrectly identify the number of channels in embedded JPEG or JPEG2000 tiles. This vulnerability may allow a local attacker with low privileges to trigger a buffer overflow, potentially leading to data corruption, system instability, or the disclosure of limited sensitive information.

Description OSIDB Bzimport 2026-07-20 17:03:25 UTC
libvips is a fast image processing library with low memory needs. The `tiffload` operation in libvips versions before and including 8.18.1 could incorrectly determine the number of channels in a JPEG or JPEG2000-encoded tile within a TIFF image, leading to a possible buffer overflow. This has been patched in version 8.18.2.
