Subject: graphicsmagick: memory allocation failure in MagickRealloc (memory.c)
If suitable for a CVE please assign one. Thanks.
Description:
Graphicsmagick is an Image Processing System.
This is an old memory failure, discovered time ago. The maintainer, Mr. Bob
Friesenhahn was able to reproduce the issue; I’m quoting his feedback about:
The problem is that the embedded JPEG data claims to have dimensions
59395×56833 and
this is only learned after we are in the JPEG reader.
But for some reasons (maybe not easy to fix) it is still not fixed.
The complete ASan output:
# gm identify $FILE
==12404==ERROR: AddressSanitizer failed to allocate 0xfb8065000 (67511930880)
bytes of LargeMmapAllocator (error code: 12)
