Description Andrej Nemec 2017-05-31 14:26:54 UTC

The readString function in util/read.c and util/old/read.c in libming 0.4.8 allows attackers to cause a denial of service via a large file that is mishandled by listswf, listaction, etc. This occurs because of an integer overflow that leads to a memory allocation error.
