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.
