User who did this - Hugh Waite (hugh.waite) 

Attached to Project - sip-router
Summary - textopsx:msg_apply_changes() can corrupt incoming TCP message buffer
Task Type - Bug Report
Category - Module
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - High
Priority - Normal
Reported Version - Development
Due in Version - Undecided
Due Date - Undecided
Details - The msg_apply_changes function in textopsx module creates a new request in pkg memory and copies it back into the main message parse buffer.
When data has been read from a TCP stream, it may include more than one message. The buffer and pointers will be corrupted if the new request is larger, causing failure to parse the subsequent messages.
