NVD Description

Note: Versions mentioned in the description apply only to the upstream bsdtar package and not the bsdtar package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

The process_extra function in libarchive before 3.2.0 uses the size field and a signed number in an offset, which allows remote attackers to cause a denial of service (crash) via a crafted zip file.
