             Summary: res_pjsip: Segfault when calling pjsip_hdr_print_on in sip_msg.c:581
                 Key: ASTERISK-27792
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27792
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_pjsip
    Affects Versions: 13.20.0
         Environment: CentOS
            Reporter: Ross Beer


Since upgrading to pjproject 2.7.2 the patch that fixed issue ASTERISK-26832 was removed and the actual fix is not present in release 2.7.2

Fixed Code:

{noformat}
PJ_DEF(int) pjsip_hdr_print_on( void *hdr_ptr, char *buf, pj_size_t len)
{
    pjsip_hdr *hdr = (pjsip_hdr*) hdr_ptr;
    if (!hdr->vptr) {
        return 0;
    }
    return (*hdr->vptr->print_on)(hdr_ptr, buf, len);
}
{noformat}

2.7.2 Code:

{noformat}
PJ_DEF(int) pjsip_hdr_print_on( void *hdr_ptr, char *buf, pj_size_t len)
{
    pjsip_hdr *hdr = (pjsip_hdr*) hdr_ptr;
    return (*hdr->vptr->print_on)(hdr_ptr, buf, len);
}
{noformat}
