Shuaibing Lu discovered that missing input validation in the ar/tar
implementations of APT, the high level package manager, could result in
denial of service when processing specially crafted deb files.

in version 1.4.10.

For the stable distribution (buster), this problem has been fixed in
version 1.8.2.1.
