"This update for libosip2 fixes several issues. These security issues
were fixed :

    have lead to a heap buffer overflow in the
    msg_osip_body_parse() function defined in
    osipparser2/osip_message_parse.c, resulting in a remote
    DoS (bsc#1034570).

  - CVE-2016-10326: In libosip2 a malformed SIP message
    could have lead to a heap buffer overflow in the
    osip_body_to_str() function defined in
    osipparser2/osip_body.c, resulting in a remote DoS
    (bsc#1034571).

  - CVE-2016-10325: In libosip2 a malformed SIP message
    could have lead to a heap buffer overflow in the
    _osip_message_to_str() function defined in

    DoS (bsc#1034572).
