Name of the Vulnerable Software and Affected Versions libming versions prior to 0.4.8

Description The issue arises from the pushdup function in util/decompile.c, which fails to perform a deep copy of a String at the top of the stack when ActionPushDuplicate is executed. This oversight makes the library susceptible to a NULL pointer dereference in getName, potentially allowing attackers to cause a denial of service by providing a crafted SWF file.

Recommendations For versions prior to 0.4.8, update to version 0.4.8 or later to resolve the issue.
