Created ImageMagick tracking bugs for this issue:

Affects: fedora-all [bug 1609943]

Comment 3 Riccardo Schirone 2018-08-07 08:33:59 EDT

Memory is allocated in the parse8BIM function in coders/meta.c and pointed by the `line` variable. However there are multiple paths that return from the function without releasing the acquired memory.
