CVE-2026-33327 Details
Description
libvips is a fast image processing library with low memory needs. The `vipsload` operation in versions before and including 8.18.0 could incorrectly determine image dimensions leading to an integer overflow and a subsequent heap-based buffer overflow. This has been patched in version 8.18.1.
A heap-based buffer overflow vulnerability has been identified in libvips versions through 8.18.0. The issue arises in the 'vipsload' operation, where incorrect determination of image dimensions can lead to an integer overflow, allowing for a buffer overflow on the heap.
Users can upgrade to libvips version 8.18.1 or later to address this vulnerability. For those unable to upgrade, it is possible to block the 'VipsForeignLoadVips' operation using 'vips_operation_block_set', available in most language bindings. Alternatively, the 'VIPS_BLOCK_UNTRUSTED' environment variable can be set to disable all 'untrusted' image decoders.
