Subject: CVE Request -- autojump: autojump profile will load random stuff
 from a directory called custom_install

Hello Kurt, Steve, vendors,

  a security flaw was found in the way autojump, a tool for faster filesystem
navigation from the command line, used to honour content of custom_install
directory when global and local autojump installations were not found,
and $SHELL variable was unset or set to different value than bash or zsh.
If an unsuspecting autojump user was tricked into running autojump script
from the directory a local attacker has write access to, this flaw could be
used for arbitrary (Python) code execution with the privileges of the user
running the autojump binary / script.

Relevant (final) upstream patches are as follows:

        Thanks also goes to Jan Pokorny for bringing this one to my attention,
        and to William Ting of autojump upstream for promptly fixing the issue.

Could you allocate a CVE identifier for this?

Thank you && Regards, Jan.
