    Package        : ant
    CVE ID         : CVE-2018-10886
    
    Danny Grander reported that the unzip and untar tasks in ant, a Java
    based build tool like make, allow the extraction of files outside a
    target directory. An attacker can take advantage of this flaw by
    submitting a specially crafted Zip or Tar archive to an ant build to
    overwrite any file writable by the user running ant.
    
    For the stable distribution (stretch), this problem has been fixed in
    version 1.9.9-1+deb9u1.
    
    We recommend that you upgrade your ant packages.
    
    For the detailed security status of ant please refer to its security
    tracker page at:
