Stack-based buffer overflow in the safe_fprintf function in tar/util.c in libarchive 3.2.1 allows remote attackers to cause a denial of service via a crafted non-printable multibyte character in a filename.
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.
