CVE-2017-16711

The swf_DefineLosslessBitsTagToImage function in lib/modules/swfbits.c in SWFTools 0.9.2 mishandles an uncompress failure, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) because of extractDefinitions in lib/readers/swf.c and fill_line_bitmap in lib/devices/render.c, as demonstrated by swfrender.
