Google: First SHA1 Collision, Cloudflare Memory Leak Incident Report

At they went over the sha-1 collision from last week;
“Hash functions compress large amounts of data into a small message digest. As a cryptographic requirement for wide-spread use, finding two messages that lead to the same digest should be computationally infeasible. Over time however, this requirement can fail due to attacks on the mathematical underpinnings of hash functions or to increases in computational power.

Today, more than 20 years after of SHA-1 was first introduced, we are announcing the first practical technique for generating a collision.”

Cloudflare released a report on the memory leak incident from late last week.
In some circumstances, their edge servers were running past the edge of a buffer and returning memory that contained private information such as, HTTP cookies, authentication tokens and more. Cloudflare went on in the report about the fix and details about the issue. For more:
