Description Marc Schiffbauer gentoo-dev 2024-02-14 10:01:43 UTC 
"A DNSSEC validation vulnerability has been discovered in various DNSSEC validating software. The vulnerability has an assigned number of CVE-2023-50387 and is referred here as the KeyTrap vulnerability.

The KeyTrap vulnerability works by using a combination of Keys (also colliding Keys), Signatures and number of RRSETs on a malicious zone. Answers from that zone can force a DNSSEC validator down a very CPU intensive and time costly validation path."

Other DNS implementations are affected as well.

I already added 1.19.1 to the tree:
