In ytnef 1.9.3, the TNEFSubjectHandler function in lib/ytnef.c allows remote attackers to cause a denial-of-service (and potentially code execution) due to a double free which can be triggered via a crafted file.
The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
