Debian DSA-5065-1 Addressed Cross-User Vulnerability in IPython

It was discovered that IPython, an enhanced interactive Python shell,
executed config files from the current working directory, which could
result in cross-user attacks if run from a directory multiple usersmay write to.

For the oldstable distribution (buster), this problem has been fixed
in version 5.8.0-1+deb10u1.

For the stable distribution (bullseye), this problem has been fixed in
version 7.20.0-1+deb11u1.

We recommend that you upgrade your ipython packages.
