Cloudflare has fixed the Cloudbleed software bug responsible for a buffer overrun problem that caused its edge servers to return private information in response to some HTTP requests. That private information included HTTP cookies, authentication tokens and HTTP POST bodies. However, SSL private keys weren’t leaked, said Cloudflare CTO John Graham-Cumming in an online post. “This happened in response to a very small number of requests in the Cloudflare system — about 1 in 3.3 million,” a Cloudflare spokesperson noted.
