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: [link moved to references]");
