SampleTable.cpp: Prevent corrupted stts block from causing
excessive memory allocation.
Details:
DataSource.h
- Added function getVector() for reading from a data source into
a Vector object, whose capacity grows only as much as needed
(in case of EOS or reading error).
SampleTable.h
- Changed the type of mTimeToSample from uint32_t* to
Vector<uint32_t>.
SampleTable.cpp
- In setTimeToSample, modified the code to use getVector()
instead of readAt(). If the input source has a corrupt
time-to-sample table size that is too big, EOS will be reached
before the whole table is read, and the return value from
getVector() will be false.
- Also, tightened the bound for the provided time-to-sample table
size to guarantee that the table does not take more than
UINT_MAX32 bytes in memory.
