Description Srikanth Balasubramanian 2026-10-06 16:49:00 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Finding 3. plug-ins/common/file-dicom.c, export_image() (~1649–1652). Wrapped width * height * bpp allocation; GEGL write exceeds buffer. SIGSEGV/ASan WRITE. Vector: export to DICOM on very large image (multi‑GB scale), not a small malicious download alone. CVSS tentative: AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:H (6.3).
