CVE-2026-3282 Details
Description
A flaw has been found in libvips 8.19.0. This vulnerability affects the function vips_unpremultiply_build of the file libvips/conversion/unpremultiply.c. Executing a manipulation of the argument alpha_band can lead to out-of-bounds read. The attack needs to be launched locally. The exploit has been published and may be used. This patch is called 7215ead1e0cd7d3703cc4f5fca06d7d0f4c22b91. A patch should be applied to remediate this issue.
A vulnerability allowing out-of-bounds read has been identified in libvips version 8.19.0. The issue arises in the unpremultiply function, where the alpha_band parameter is not properly validated before being used as a direct index for pixel data. This oversight can lead to unauthorized memory access, specifically a heap-buffer-overflow, which is reported by AddressSanitizer. The vulnerability must be exploited locally, and a proof-of-concept exploit is available.
Users are advised to update to libvips version 8.19.1 or later, where this vulnerability has been fixed.
