In this blog post by Soatok, they detail their experience with a vulnerability found in FreeSWITCH software. The issue was related to buffer overflow and memory corruption due to poor handling of input validation within C code. Although SignalWire (formerly FreeSWITCH) responded eventually by fixing the problem on GitHub, they were slow in addressing it and did not release a patch for their users promptly. Soatok suggests potential solutions such as rebuilding from source or blocking public HTTP access to mitigate risks until an official update arrives. They also express concerns about broader issues with incentives and security practices within the industry.
