CVE-2015-6360 libsrtp: improper handling of CSRC count and extension header length in RTP header
Last modified: 2016-10-27 05:46:44 EDT
Randell Jesup and the Firefox team discovered that srtp, Cisco's reference implementation of the Secure Real-time Transport Protocol (SRTP), does not properly handle RTP header CSRC count and extension header length. A remote attacker can exploit this vulnerability to crash an application linked against libsrtp, resulting in a denial of service. References: http://seclists.org/bugtraq/2016/Apr/11

asterisk-1.8.32.3-2.el6, libsrtp-1.5.4-3.el6, pjproject-2.3-7.el6 has been pushed to the Fedora EPEL 6 stable repository. If problems still persist, please make note of it in this bug report.
Was it necessary to bump the libsrtp.so name to libsrtp.so.1 in this update?
That's the soname for the 1.5 series from upstream, so yes.
