Add explicit LZW decompression stack size limit. Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is constructed correctly. It's even less than that, see e.g. libarchive code comment for a better size upper bound: http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121 This patch adds explicit stack size limit, enforced when stack is realloced. An alternative is to ensure that code < state->prefix[code - 256] when traversing prefix table. Such check is less efficient and should not be required if prefix table is constructed correctly in the first place. * src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it.
