Comment 1 Sam James archtester gentoo-dev Security 2020-06-07 16:59:31 UTC
Patch for CVE-2020-12672: http://hg.code.sf.net/p/graphicsmagick/code/rev/50395430a371

Note that there are more issues (unrelated):
* http://hg.code.sf.net/p/graphicsmagick/code/rev/83b4d2b4b873

"Terminate reading when a pixel cache resource limit is hit rather than moving on to heap buffer overflow.  Fixes oss-fuzz 20045, 20318, 21956"

* http://hg.code.sf.net/p/graphicsmagick/code/rev/b0aa53a5f970

"Heap-buffer-overflow in ImportGrayQuantumType" and oss-fuzz, "Heap-buffer-overflow in InsertRow" which are both from the samecause.
