[Shlomi Gutman (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-22920?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Shlomi Gutman updated ASTERISK-22920:
-------------------------------------

    Attachment: ldd.log
                debug.log
                backtrace_ldd.log

Ha, i gathered new info from other server.
Centos one(info in envirement info of bug)
asterisk 1.8.14.0

ldd.log is after i installed it i got more info, and as i see it goes to pointer, that was probably freed before and thus it fails.
(usr/sbin/asterisk: munmap_chunk(): invalid pointer: XXXXXXXXXXXXXX ****)
backtrace_ldd.log is info from core

debug.log is when i set debug 10, though i get less info from ldd so you have ldd.log with backtrace and it's from other crash.

On this system it's 100% crashes.

>         Environment: CentOS release 5.8 (Final)  kernel 2.6.18-308.24.1.el5 64bit, libsrtp 1.4.2(compiled manually)  with 1.8.14 with and without patch (https://issues.asterisk.org/jira/browse/ASTERISK-18345)

> Steps to reproduce:
> 1)Asterisk with self signed certificates or GoDaddy certificates
> 2)Extension connected with TLS transport (behind NAT in our case)
> 3)Route incoming call to that extension, while forward call from it without answering (302 - FORWARD)
> 4)Crash
> I know that this bug may be related to srtp, but as we see it was not developed and maintained for a long time and as asterisk srtp based on itץ
> I think at least it should crash the call only, but not whole asterisk.
