The archive_wstring_append_from_mbs function in archive_string.c in libarchive 3.2.2 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted archive file.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
