The attacker can use this flaw to cause many dictionary entries to be created.
For Debian 10 buster, this problem has been fixed in version 1.0.17-1+deb10u1.
We recommend that you upgrade your python-ipaddress packages.
For the detailed security status of python-ipaddress please refer to its security tracker page at: [link moved to references]
Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
