The Bitcoin Core project has disclosed two security vulnerabilities that could have affected the stability of the Bitcoin network. The first one, classified as having a high severity level, could have caused an assertion crash of the network via a message spam attack. The second one, with a low severity level, was linked to Miniupnp, a Universal Plug and Play library used by Bitcoin Core, and could cause a node to run out of memory. These two vulnerabilities were already fixed in 2021 with the release of Bitcoin Core v22.0 but were only recently revealed to the public.
