A fix was pushed into the master branch but not yet published.
Overview
Affected versions of this package are vulnerable to Integer Overflow in the bundled libvips GIF loader (VipsForeignLoadNsgif), which can miscompute image dimensions on 32-bit systems. An attacker can crash the process by supplying a GIF whose dimensions overflow the size calculation. Exploitation affects only 32-bit systems and requires the application to decode an untrusted GIF through sharp.
Workaround
This vulnerability can be avoided by blocking the GIF loader through sharp's block() for the VipsForeignLoadNsgif operation, or by setting the VIPS_BLOCK_UNTRUSTED environment variable, so untrusted GIF images are not decoded.
