How to upgrade glibc ?

Hi,

My ctm is using linux 2.6.37 and filesystem from DVRRDK2.x.   The hardware is DM8167.

By using the ls -l /lib/libc.so.6 they learned that the glibc version=2.4.

But recently it reported that glibc version<2.18 has risks of being attacked. So ctm simply want to update to the glibc version later than 2.18.

Here comes the question: How to upgrade glibc? Can I simply copy a new glibc file (libc.so.6) from later SW e.x. Sitara SDK? Or it must be compiled w/ the toolchain that ctm uses?

Please kindly add your comments.

 

BR,

Eason
