I wrote a fuzzer for libsrtp for purely recreational reasons. I reported the bugs I found to the libsrtp security mailing list several months ago. Finally those bugs seem to have been fixed in the git master tree. Apparently these findings and fixes for them don’t seem to prompt a new release. Cisco has stopped responding and I don’t know what the deal is. I recently also contacted Cisco Talos but they didn’t respond at all. So I’ve decided to publish my fuzzers. I put considerable effort in it but I’m now tired of this project because nobody really seems to care, and I am abandoning it. Underwhelming experience, exception to the rule.
EDIT 23/03: Removed invalid information about Talos. My bad.
