Description

A double-free issue has been found in libarchive >= 3.1.0 and <=3.3.3, in the parse_codes() function in archive_read_support_format_rar.c. An attacker can use a specially crafted RAR file to cause a call to realloc with a size of 0, effectively freeing the memory which will be freed again at a later time.
