A vulnerability has been discovered in jupyter_core which could allow for the execution of code as another user.
|Package||dev-python/jupyter_core on all architectures|
|Affected versions||< 4.11.2|
|Unaffected versions||>= 4.11.2|
jupyter_core contains core Jupyter functionality.
jupyter_core trusts files for execution in the current working directory without validating ownership of those files.
By writing to a directory that is used a the current working directory for jupyter_core by another user, users can elevate privileges to those of another user.
There is no known workaround at this time.
All jupyter_core users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-python/jupyter_core-4.11.2"
