We are having the Asterisk version of 1.4.31. We would like to patch due to the vulnerability reported as
Exploitable Stack and Heap Array Overflows. To fix this issue Asterisk had given the patch “http://downloads.asterisk.org/pub/security/AST-2011-002-1.4.diff”.
Could anyone help us how to do the patching. This file looks as a configuration file., Whether we need to replace it with the existing file. If so please specify which file to be replaced.
