Description

Problem Description:

Flaws in libarchive's handling of symlinks and hard links

allow overwriting files outside the extraction directory,

or permission changes to a directory outside the extraction

directory.

Impact:

An attacker who can control freebsd-update's or portsnap's

input to tar(1) can change file content or permissions on

files outside of the update tool's working sandbox.

  • freebsd-upgrade-base-10_2-release-p23
