list_item_verbose in tar/util.c in libarchive through 3.7.7 does not check an strftime return value, which can lead to a denial of service or unspecified other impact via a crafted TAR archive that is read with a verbose value of 2. For example, the 100-byte buffer may not be sufficient for a custom locale.
