NVD Description

Note: Versions mentioned in the description apply only to the upstream rar package and not the rar package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

Directory Traversal exists in RAR 4.x and 5.x because an unpack operation follows any symlinks, including symlinks contained in the archive. This allows remote attackers to write to arbitrary files via a crafted archive.
