| | | | | | | | | | | | | | | | | Causes a divide-by-zero in the rare case where: - the file has an audio stream, - the first audio frame isn't within the first BRP_BASF_LOOKAHEAD frames, - an audio frame is encountered later, and - its chunk header (except num_blocks) contains all zeros (matching the uninitialised structure in the context) The decoder will discard any garbage data, so the check isn't really needed.

* avformat/apngdec: Check fcTL chunk length when reading headerAndreas Rheinhardt2020-11-03
| | | | | | | | | | Reading the header terminates when an fcTL chunk is encountered in which case read_header returned success without checking the length of said chunk. Yet when read_packet processes this chunk, it checks for the length to be 26 and errors out otherwise. So do so when reading the header, too.

* avformat/apngdec: Fix size/overflow checksAndreas Rheinhardt2020-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | apng data consists of parts containing a small header (including a four-byte size field) and a data part; the size field does not account for everything and is actually twelve bytes short of the actual size. In order to make sure that the size fits into an int, the size field is checked for being > INT_MAX; yet this does not account for the + 12 and upon conversion to int (which happens when calling append_extradata()), the size parameter can still wrap around. In this case the currently used check would lead to undefined signed integer overflow. Furthermore, append_extradata() appends the new data to the already existing extradata and therefore needs to make sure that the combined size of new and old data as well as padding fits into an int. The check used for this is "if (old_size > INT_MAX - AV_INPUT_BUFFER_PADDING_SIZE - new_size)". If new_size is > INT_MAX - AV_INPUT_BUFFER_PADDING_SIZE the right side becomes negative if the types are signed (as they are now); yet changing this to "if (new_size > INT_MAX - AV_INPUT_BUFFER_PADDING_SIZE - old_size)" is better as this also works for unsigned types (where it is of course presumed that INT_MAX is replaced by the corresponding maximum for the new type). Both of these issues have been fixed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avformat/apngdec: Return error for incomplete headerAndreas Rheinhardt2020-11-03
| | | | | | | | | | | | | | If avio_read() could read anything, it returns the number of bytes read, even if it could not read as much as the caller desired. apng_read_header() only checked the return value of its avio_read() calls for being negative and this meant that it was possible for an incomplete header to not be detected. The return value of the last successfull call has been returned instead. This commit changes this.

* fate: Add test for Musepack SV8 decodingAndreas Rheinhardt2020-10-31
| | | | | | | | | | | | | | | While the FATE suite contains a sample file for Musepack 8, it did not use it to test the decoder; it is only used in the mpc8-demux test that tests the demuxer via streamcopy. Therefore this commit adds an actual encoder test. The test uses the framecrc output, because Musepack SV8 is an encoder that returns multiple frames for a single packet, so that timing information in the test output is valueable. Output seeking has been used in order to limit the size of the ref file as well as to test this codepath for the first time. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
