Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-apps/file < 5.15 >= 5.15 Description =========== BEGIN regular expression in the awk script detector in magic/Magdir/commands uses multiple wildcards with unlimited repetitions.
