Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2022-09-28 22:53:39 UTC 
CVE-2022-1270:

In GraphicsMagick, a heap buffer overflow was found when parsing MIFF.

"This issue is addressed by Mercurial changeset 16689:94f4bcf448ad and the latest development snapshot (GraphicsMagick-1.4.020220326.tar.xz)."

But not sure how that relates to versions in tree or if the fix has
made it into a release yet.
Comment 1 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2022-09-28 23:02:04 UTC 
Patch is https://hg.osdn.net/view/graphicsmagick/GM/rev/94f4bcf448ad and although it appears to not be in a release based on NEWS, the actual patch is there in 1.3.38. Huh.

But it is in ChangeLog:
"""
2022-03-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * version.sh: Prepare for 1.3.38 release.

        * Makefile.am (release, snapshot): Generate SHA-256 checksums as a
        by-product of 'make snapshot' or 'make release'.

        * www/download.rst: Add documentation regaring SHA-256 checksums.

        * NEWS.txt: Update the news again.

        * coders/miff.c (ReadMIFFImage): Validate claimed bzip2-compressed
        row length prior to reading data into fixed size buffer.
        Addresses SourceForge bug #664 "[bug]Heap buffer overflow when
        parsing MIFF".  This severe bug only impacts builds with BZLIB
        support.
