1.11.0- Upgrade github.com/coredns/coredns to this version or later
Description
An issue was discovered in CoreDNS through 1.10.1. There is a vulnerability in DNS resolving software, which triggers a resolver to ignore valid responses, thus causing denial of service for normal resolution. In an exploit, the attacker could just forge a response targeting the source port of a vulnerable resolver without the need to guess the correct TXID.
Affected versions
Go
| Package | Vulnerable | Fixed in |
|---|---|---|
| github.com/coredns/coredns | < 1.11.0 |
1.11.0 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
github.com/coredns/coredns Go → 1.11.0

go get github.com/coredns/coredns@v1.11.0 && go mod tidy
