An issue was discovered in libming 0.4.8. There is a heap-based buffer over-read in the function writePNG in the file util/dbl2png.c of the dbl2png command-line program. Because this is associated with an erroneous call to png_write_row in libpng, an out-of-bounds write might occur for some memory layouts.
A heap-based buffer over-read was discovered in decompileJUMP function in util/decompile.c of libming v0.4.8. A crafted input can cause segmentation faults, leading to denial-of-service, as demonstrated by swftocxx.
libming 0.4.8 has a NULL pointer dereference in the getName function of the decompile.c file, a different vulnerability than CVE-2018-7872 and CVE-2018-9165.
libming 0.4.8 has a NULL pointer dereference in the getString function of the decompile.c file, related to decompileSTRINGCONCAT. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted swf file.
In libming 0.4.8, there is an excessive memory allocation attempt in the readBytes function of the util/read.c file, related to parseSWF_DEFINEBITSJPEG2. Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted swf file.
There is a memory leak in util/parser.c in libming 0.4.8, which will lead to a denial of service via parseSWF_DEFINEBUTTON2, parseSWF_DEFINEFONT, parseSWF_DEFINEFONTINFO, parseSWF_DEFINELOSSLESS, parseSWF_DEFINESPRITE, parseSWF_DEFINETEXT, parseSWF_DOACTION, parseSWF_FILLSTYLEARRAY, parseSWF_FRAMELABEL, parseSWF_LINESTYLEARRAY, parseSWF_PLACEOBJECT2, or parseSWF_SHAPEWITHSTYLE.
