-Subject: Bug 767873 - (CVE-2016-4994) Multiple Use-After-Free when parsing...
-
-...XCF channel and layer properties
-
-The properties PROP_ACTIVE_LAYER, PROP_FLOATING_SELECTION,
-PROP_ACTIVE_CHANNEL saves the current object pointer the @info
-structure. Others like PROP_SELECTION (for channel) and
-PROP_GROUP_ITEM (for layer) will delete the current object and create
-a new object, leaving the pointers in @info invalid (dangling).
-
-Therefore, if a property from the first type will come before the
-second, the result will be an UaF in the last lines of xcf_load_image
-(when it actually using the pointers from @info).
-
-I wasn't able to exploit this bug because that
-g_object_instance->c_class gets cleared by the last g_object_unref and
-GIMP_IS_{LAYER,CHANNEL} detects that and return FALSE.
-
-(cherry picked from commit 6d804bf9ae77bc86a0a97f9b944a129844df9395)
