    CVE-2019-6976

    Published: 26 Jan 2019Last Modified: 7 Aug 2026

    Summary:

    Details: 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.
