[bitcoindev] Public disclosure of 2 vulnerabilities affecting Bitcoin Core < v22.0

Hi everyone, 

Today we are releasing 2 security advisories for the Bitcoin Core project. 
Those bugs affect versions of Bitcoin Core before (and not including) 
v22.0. 

This is part of the gradual adoption by the project of a new vulnerability 
disclosure policy. 

The policy and the 2 security advisories can be found on the project's 
website at https://bitcoincore.org/en/security-advisories . 

We will follow up later in August to publicly disclose vulnerabilities 
fixed in version v23.0. And then in September to disclose those fixed in 
version v24.0, and so on until we run out of unmaintained versions to 
disclose vulnerabilities for. The announced policy will then start to be 
observed for new versions.

Niklas Gögge

You should say which two security vulnerabilities the newly disclosed ones
actually are. The link does not make that clear at all.

The disclosure dates should also please be included on that page.

For clarity, the advisories appear to be in reverse chronological order of their posting.

The two newest disclosures are the ones announced in OP

[Disclosure of remote crash due to addr message spam](https://bitcoincore.org/en/2024/07/31/disclose-addrman-int-overflow/)

Nodes could be spammed with addr messsages, which could be used to crash them. A fix was released on September 14th, 2021 in Bitcoin Core v22.0.

[Disclosure of the impact of an infinite loop bug in the miniupnp dependency](https://bitcoincore.org/en/2024/07/31/disclose-upnp-oom/)

Nodes could be crashed by a malicious UPnP device on the local network. A fix was released on September 14th, 2021 in Bitcoin Core v22.0.
