libvips is a demand-driven, horizontally threaded image processing library. The heifsave operation could incorrectly determine the presence of an alpha channel in an input when it was not possible to determine the colour interpretation, known internally within libvips as "multiband". There aren't many ways to create a "multiband" input, but it is possible with a well-crafted TIFF image. If a "multiband" TIFF input image had 4 channels and HEIF-based output was requested, this led to libvips creating a 3 channel HEIF image without an alpha channel but then attempting to write 4 channels of data. This caused a heap buffer overflow, which could crash the process. This vulnerability is fixed in 8.16.1.

The remote Debian 12 host has packages installed that are affected by a vulnerability as referenced in the dsa-5915 advisory.

    Package        : vips     CVE ID         : CVE-2025-29769

    A heap-based buffer overflow vulnerability was discovered in vips, an     fast image processing library designed with efficiency in mind, which     may result in denial of service (application crash) if a specially     crafted TIFF image file is processed.

    For the stable distribution (bookworm), this problem has been fixed in     version 8.14.1-3+deb12u2.

    We recommend that you upgrade your vips packages.
