Debian LTS Advisory DLA-3424-1 [email protected]

Package : python-ipaddress
Version : 1.0.17-1+deb10u1
CVE ID : CVE-2020-14422

Martin Wennberg discovered that python-ipaddress, a backport of Python 3's
ipaddress module, improperly computed hash values in the IPv4Interface and
IPv6Interface classes, which might allow a remote attacker to cause a
denial of service if an application is affected by the performance of a
dictionary containing IPv4Interface or IPv6Interface objects. The attacker
can then 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.
