Title: jupyter_core: Arbitrary Code Execution
Date: January 11, 2023
Bugs: #878497
ID: 202301-04
Synopsis
A vulnerability has been discovered in jupyter_core which could allow
for the execution of code as another user.
Background
jupyter_core contains core Jupyter functionality.
Affected packages
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-python/jupyter_core < 4.11.2 >= 4.11.2
Description
jupyter_core trusts files for execution in the current working directory
without validating ownership of those files.
Impact
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.
Workaround
There is no known workaround at this time.
Resolution
All jupyter_core users should upgrade to the latest version:
emerge --sync
emerge --ask --oneshot --verbose “>=dev-python/jupyter_core-4.11.2”
