bsdtar in libarchive before 3.2.0 returns a success code without filling the entry when the header is a split file in multivolume RAR, which allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted rar file.

Weakness

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.
