Overview
Affected versions of this package are vulnerable to Integer Overflow leading to a heap buffer overflow in the bundled libvips VIPS loader (VipsForeignLoadVips), which can miscompute image dimensions. An attacker can corrupt heap memory and crash the process, with a possibility of code execution, by supplying a VIPS (.vips) image whose dimensions overflow the size calculation. Exploitation requires the application to decode an untrusted VIPS image through sharp.
Workaround
This vulnerability can be avoided by blocking the VIPS loader through sharp's block() for the VipsForeignLoadVips operation, or by setting the VIPS_BLOCK_UNTRUSTED environment variable, so untrusted VIPS images are not decoded.
