[asterisk-bugs] [JIRA] (ASTERISK-29024) pjsip: Route Header in Cancel request incorrectly set

[nappsoft (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-29024?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=252960#comment-252960 ] 

nappsoft commented on ASTERISK-29024:
-------------------------------------

the change in res_pjsip_nat.c is exactly the same like my patch => so I've alredy tested this
the change in the pjsip library I'd already applied (forgot to mention that) => so I've already tested this part of your patch as well
the change in res_pjsip_transport_websocket.c shouldn't influence anything in our environment... so it makes no sense for me to check that

So in short: I guess that your patch should give exactly the same results as mine (at least for the cases I was testing)

> When I initiate a call using PJSIP and Cancel the call while it's still ringing the Route-Header seems to be sent incorrectly. It looks like it's a pointer to a memory region that got overwritten. I saw internal IP Addresses in there aswell as some other stuff like "Route: <sip:}". The "Route: <sip:" is always set properly, just the part after the sip is never set correctly and also the closing ">" is always missing.
> As the memory region that it reads from can't be controlled it might happen that confidential data like a password is exposed over this.
