formats, including certain tar variants, several cpio formats, and both
BSD and GNU ar variants.
Multiple vulnerabilities have been discovered in libarchive. Please
review the CVE identifiers referenced below for details.
A remote attacker could entice a user or automated process to open a
specially crafted archive using an application linked against libarchive,
possibly resulting in execution of arbitrary code with the privileges of
the process or a Denial of Service condition.
There is no known workaround at this time.
All libarchive users should upgrade to the latest version:
