Andreas Rheinhardt	5b33f523d7	avformat/aaxdec: Fix potential integer overflow The AAX demuxer reads a 32bit number containing the amount of entries of an array and stores it in an uint32_t. Yet when iterating over this array, a loop counter of type int is used. This leads to undefined behaviour if the amount of entries is not in the range of int; to avoid this, it is generally good to use the same type for the loop counter as for the variable it is compared to. This is done in one of the two loops affected by this. In the other loop, the undefined behaviour can begin even earlier: Here the loop counter is multiplied by an uint16_t which can overflow as soon as the loop counter is > 2^15. Using an unsigned type would avoid the undefined behaviour, but truncation would still be possible, so use an uint64_t. Also use an uint32_t for a variable containing an index in said array. This fixes Coverity issue #1466767. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	5 years ago
