Description Vincent Danen 2013-06-04 15:46:57 UTC

A buffer overflow flaw was reported [1] in libsrtp, 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.  This could allow for a crash of a client linked against libsrtp (like asterisk or linphone).

A pull request in git [2] has a patch to correct this issue.
