Details
As written in the advisory (Markdown source, shown as plain text).
### Description
When using the `NoPrivateNetworkHttpClient`, some internal information is still leaking during host resolution, which leads to possible IP/port enumeration.
### Resolution
The `NoPrivateNetworkHttpClient` now filters blocked IPs earlier to prevent such leaks.
The fisrt patch for this issue is available [here](https://github.com/symfony/symfony/commit/296d4b34a33b1a6ca5475c6040b3203622520f5b) for branch 5.4.
The second one is available [here](https://github.com/symfony/symfony/commit/b4bf5afdbdcb2fd03da513ee03beeabeb551e5fa) for branch 5.4 also.
### Credits
We would like to thank Linus Karlsson and Chris Smith for reporting the issue and Nicolas Grekas for providing the fix.
