Description

libvips before 8.7.4 generates output images from uninitialized memory locations when processing corrupted input image data because iofuncs/memory.c does not zero out allocated memory. This can result in leaking raw process memory contents through the output image.

How to fix

Upgrade to a fixed version: libvips 8.7.4. Check the vendor advisory for mitigations.
