An improper link resolution flaw can occur while extracting an archive
leading to changing modes, times, access control lists, and flags of a file
outside of the archive. 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 gain more privileges in a
system.
