Stack-based buffer overflow in the parse_device function in archive_read_support_format_mtree.c in libarchive before 3.2.1 allows remote attackers to execute arbitrary code via a crafted mtree file.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
