--------------------------------------

             Summary: SIGSEGV when pjsip show history encounters IPV6 address
                 Key: ASTERISK-28854
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28854
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_pjsip
    Affects Versions: 17.3.0
         Environment: Linux
            Reporter: Roger James
            Severity: Trivial


In  res_pjsip_history.c

/*! \brief An item in the history */
struct pjsip_history_entry {
	...
	/*! \brief Source address */
	pj_sockaddr_in src; This is only long enough to hold an ipv4 address
	/*! \brief Destination address */
	pj_sockaddr_in dst; Same herw
       ...
};

Calls like these ovefloow the fileds when an IPV6 address is encountered.

/*! \brief PJSIP callback when a SIP message is transmitted */
static pj_status_t history_on_tx_msg(pjsip_tx_data *tdata)
{
        struct pjsip_history_entry *entry;
        ...
        pj_sockaddr_cp(&entry->src, &tdata->tp_info.transport->local_addr);
        pj_sockaddr_cp(&entry->dst, &tdata->tp_info.dst_addr);

Result SIGSEGV.
