Update zlib 1.2.11 to 1.2.12

Colibri VF61
Linux BSP 2.8.6
Build with yocto 2.4 (rocko)

Dear community,
I need to be update zlib from 1.2.11 to 1.2.12 in my running environment. I found the version in the openembedded lay endex → OpenEmbedded Layer Index - zlib .
It is available for the current yocto project.

It is possible to added this to my yocto version (2.4)?
And how can I replace the 1.2.11 with 1.2.12?
