NVD Description

Note: Versions mentioned in the description apply only to the upstream libarchive package and not the libarchive package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

An improper link resolution flaw while extracting an archive can lead to changing the access control list (ACL) of the target of the link. An attacker may provide a malicious archive to a victim user, who would trigger this flaw when trying to extract the archive. A local attacker may use this flaw to change the ACL of a file on the system and gain more privileges.
