libSRTP is an Open-source implementation of the Secure Real-time Transport Protocol.
A flaw was found in how the crypto_policy_set_from_profile_for_rtp() function applies cryptographic profiles to an srtp_policy in libSRTP.
A remote attacker could exploit this vulnerability to crash an application linked against libSRTP, resulting in Denial of Service.
There is no known workaround at this time.
All libSRTP users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-libs/libsrtp-1.4.4_p20121108-r1"
