bash replacement ...

bash replacement ...

[terry white]

... ciao:

     when the bash vulnerability was announced i built the 'new' patched 
version. in my case, two.  though, not automatic, not really problematic.
however, when i tried to replace the running 'bash', the system disallowd 
that operation.

     so, i booted a rescue system, and did the replacement that way.

     is there a way i could have done that on the native system ?

     thanks ...

You've to rename the running binary instead of replacing it but in one 
single execution, so later you can delete the old one.

for example:

mv /bin/bash /bin/bash.orig; cp /usr/src/bash_source/build/bash 
/bin/bash; chmod 755 /bin/bash

try it..

Cheers.

you can always do:

cp /bin/bash /bin/bash.old
cp -f new/bash /bin/bash

It works :)
