Description Vincent Danen 2013-01-22 22:03:23 UTC
Fabian Yamaguchi reported a read buffer overflow flaw in libarchive on 64-bit systems where sizeof(size_t) is equal to 8.  In the archive_write_zip_data() function in libarchive/archive_write_set_format_zip.c, the "s" parameter is of type size_t (64 bit, unsigned) and is cast to a 64 bit signed integer.  If "s" is larger than MAX_INT, it will not be set to "zip->remaining_data_bytes" even though it is larger than "zip->remaining_data_bytes", which leads to a buffer overflow when calling deflate().

This can lead to a segfault in an application that uses libarchive to create ZIP archives.
