NewCVE-2025-59933 (opens in a new tab)How to fix?
Upgrade libvips/libvips to version 8.17.2 or higher.
Overview
Affected versions of this package are vulnerable to Buffer Over-read in the pdfload process, if compiled with support for PDF input via Poppler. An attacker can cause the application to read beyond the bounds of allocated memory by submitting a specially crafted PDF document with media headers that define a width but not a height.
Note: Using libvips versions compiled with support for PDF input via PDFium or without support for PDF input at all are unaffected.
Workaround
This vulnerability can be mitigated by blocking the VipsForeignLoadPdf operation via vips_operation_block_set or by setting the VIPS_BLOCK_UNTRUSTED environment variable at runtime.
