asdcplib (aka AS-DCP Lib) 2.13.1 has a heap-based buffer over-read in ASDCP::TimedText::MXFReader::h__Reader::MD_to_TimedText_TDesc in AS_DCP_TimedText.cpp in libasdcp.so.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
