Heap-based buffer overflow in the DecodeImage function in libwmf 0.2.8.4 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted "run-length count" in an image in a WMF file.

A heap buffer overflow flaw was found in the way the libwmf library processed WMF files containing BMP images. A specially crafted WMF file could cause an application using libwmf to crash or, possibly, execute arbitrary code.
