For me it is a no-dsa one due to policy.xml forbidding such big file So will like to downgrade to minor and will made a point release rouca > > For further information see: > > [0] https://security-tracker.debian.org/tracker/CVE-2025-62171 > https://www.cve.org/CVERecord?id=CVE-2025-62171 > [1] > https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-9pp9-cfwx-54rm > [2] > https://github.com/ImageMagick/ImageMagick/commit/cea1693e2ded51b4cc91c70c54096cbed1691c00 > [3] > https://github.com/ImageMagick/ImageMagick6/commit/456771fae8baa9558a1421ec8d522e6937d9b2d7 > > Please adjust the affected versions in the BTS as needed. > > Regards, > Salvatore >
