Updated srtp package fixes security vulnerability:

Fernando Russ from Groundworks Technologies reported a buffer
overflow flaw in srtp, Cisco’s reference implementation
of the Secure Real-time Transport Protocol (SRTP), in how
the crypto_policy_set_from_profile_for_rtp() function applies
cryptographic profiles to an srtp_policy. A remote attacker could
exploit this vulnerability to crash an application linked against
libsrtp, resulting in a denial of service (CVE-2013-2139).
