CVE-2019-6976 (CCN-156218)

Assigned:2019-01-18
Published:2019-01-18
Updated:2020-08-24
Summary: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.
