Short explanation

Bastille through 1.4.4 contains a symlink following vulnerability in the cp.sh, rcp.sh and jcp.sh subcommands. This flaw allows jailed users to escape jail isolation.

Why does it matter?

Attackers inside a jail can plant symlinks pointing to host paths or other jail roots. This causes administrator-run copies to overwrite or read host files with root privileges.
