Bugzilla Automation <bugzilla@FreeBSD.org> has asked freebsd-desktop (Team)
<desktop@FreeBSD.org> for maintainer-feedback:
Bug 294061: graphics/png: Security Update to 1.6.56
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=294061



--- Description ---
As reported through oss-security mailing list with:

"libpng 1.6.56: Two high-severity vulnerabilities fixed: CVE-2026-33416,
CVE-2026-33636"
https://www.openwall.com/lists/oss-security/2026/03/26/1

As I see it, libpng-1.6.56-apng.patch is not yet available, so the attached
patch is only partially and building the ports is not possible yet.
