Drop the vendor soname-revert patch: the 6.9.13.58 tarball already sets
MAGICK_LIBRARY_CURRENT=7, matching the libraries shipped so far
Drop the TuxCare backports for CVE-2026-86420, CVE-2026-86421,
CVE-2026-93586, CVE-2026-93587, CVE-2026-93588, CVE-2026-106571,
CVE-2026-106572, CVE-2026-106573, CVE-2026-106577, CVE-2026-106578,
CVE-2026-106579, CVE-2026-106580, CVE-2026-107208 and CVE-2026-107210: all
are fixed in the 6.9.13.58 tarball, verified against the extracted source
Keep the CVE-2026-45664 backport: both MNG_MAX_LOOP_OPS abort paths in
coders/png.c still leak the chunk buffer in 6.9.13.58
Keep the MSL empty-image crash fix (partial backport of upstream fde1f305,
not present in the legacy 6.x line)
