An memory leak issue was discovered in AP4_StdcFileByteStream::Create in mp42ts in Bento4 v1.6.0-639, allows attackers to cause a denial of service via a crafted file.
Hi, developers of Bento4:
In the test of the binary mp42ts instrumented with ASAN. There are some inputs causing memory leaks. Here is the ASAN mode output:

=================================================================
