It is recommended that administrators running ipython check for an updated version of the software for their operating system. - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 - - ------------------------------------------------------------------------- Debian LTS Advisory DLA-2896-1 debian-lts@lists.debian.org https://www.debian.org/lts/security/ Chris Lamb January 24, 2022 https://wiki.debian.org/LTS - - ------------------------------------------------------------------------- Package : ipython Version : 5.1.0-3+deb9u1 CVE ID : CVE-2022-21699 Debian Bug : #1004122 It was discovered that there was a potential arbitrary code execution vulnerability in IPython, the interactive Python shell. This issue stemmed from IPython executing untrusted files in the current working directory. According to upstream: Almost all versions of IPython looks for configuration and profiles in current working directory. Since IPython was developed before pip and environments existed, it was used a convenient way to load code/packages in a project dependant way. In 2022, it is not necessary anymore, and can lead to confusing behavior where for example cloning a repository and starting IPython or loading a notebook from any Jupyter-Compatible interface that has ipython set as a kernel can lead to code execution. To address this problem, the current working directory is no longer searched for profiles or configuration files. For Debian 9 "Stretch", this problem has been fixed in version 5.1.0-3+deb9u1. We recommend that you upgrade your ipython packages.
