------------------------------------------------------------------------- Debian LTS Advisory DLA-3424-1 [email protected] https://www.debian.org/lts/security/ Guilhem Moulin May 16, 2023 https://wiki.debian.org/LTS
-------------------------------------------------------------------------

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.

For the detailed security status of python-ipaddress please refer to its security tracker page at:
