Category:Debian Local Security Checks
Title:Debian: Security Advisory (DLA-3424-1)
Summary:The remote host is missing an update for the Debian 'python-ipaddress' package(s) announced via the DLA-3424-1 advisory.
Description:Summary:
The remote host is missing an update for the Debian 'python-ipaddress' package(s) announced via the DLA-3424-1 advisory.

Vulnerability Insight:
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 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]
