[asterisk-bugs] [JIRA] (ASTERISK-28854) SIGSEGV when pjsip show history encounters IPV6 address

Roger James updated ASTERISK-28854:
-----------------------------------

    Description: 
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 oveflow the fields 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.

Fix is.


/*! \brief Source address */
        union {
	           pj_sockaddr_in src;
                   pj_dockaddr_in6 src6;
        };

	/*! \brief Destination address */
	pj_sockaddr_in dst; Same fix here.
       ...
