Summary
Details

ARM astcenc 3.2.0 is vulnerable to Buffer Overflow. When the compression function of the astc-encoder project with -cl option was used, a stack-buffer-overflow occurred in function encode_ise() in function compress_symbolic_block_for_partition_2planes() in "/Source/astcenc_compress_symbolic.cpp".
