how an hacker can bypass a chrooted environement ?

I was wondering how an attacker can bypass a chrooted environement. A
(common) technique consist in finding a vulnerable program (in the
chrooted environnement) and injecting it a shellcode (i.e
../../../../../../../bin/bash for ex.)  by BoF.  But normally, in the
chrooted environement, you volontarily add only necessary tools (like
ls, cat, less...), and vulnerable softwares are uncommon...

So... how do they this "exploit" of bypassing the chroot ?

Thanks in advance
