Debian LTS: Security Advisory for ipython (DLA-2896-1)

The remote host is missing an update for the 'ipython' package(s) announced via the DLA-2896-1 advisory.

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.

'ipython' package(s) on Debian Linux.

Checks if a vulnerable package version is present on the target host.

For Debian 9 'Stretch', this problem has been fixed in version 5.1.0-3+deb9u1. We recommend that you upgrade your ipython packages.
