Descriptions

Buffer overflow in srtp.c in libsrtp in srtp 1.4.5 and earlier allows remote attackers to cause a denial of service (crash) via vectors related to a length inconsistency in the crypto_policy_set_from_profile_for_rtp and srtp_protect functions.

Desbordamiento de búfer en srtp.c en libsrtp en srtp 1.4.5 y anteriores permite a atacantes remotos provocar una denegación de servicio (caída) a través de vectores relacionados con una inconsistencia en la longitud de las funciones crypto_policy_set_from_profile_for_rtp y srtp_protect.

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.
