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).

srtp was updated to fix a buffer overflow flaw that allowed 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. (CVE-2013-2139).

A buffer overflow in srtp was fixed which could potentially be used by attackers to crash srtp using applications and potentially execute code (CVE-2013-2139, bnc828009).

The remote host is affected by the vulnerability described in GLSA-201405-02 (libSRTP: Denial of Service)

    A flaw was found in how the crypto_policy_set_from_profile_for_rtp()       function applies cryptographic profiles to an srtp_policy in libSRTP.
  Impact :

    A remote attacker could exploit this vulnerability to crash an       application linked against libSRTP, resulting in Denial of Service.
  Workaround :

    There is no known workaround at this time.
