How to apply security patch on asterisk

Hi Team,

I want to update security patch on asterisk server 1.4.x.

Kindly provide me some command or document so I can apply patches on my asterisk servers.

Thanks

The way you would patch anything else. Go in to the source directory for Asterisk. Put the patch file in there and then do:
patch -p0 < patch_file_name.

Thanks Dovid

I check to patch and its working fine.

Thanks a lot.
