{"id":"GHSA-hg35-mp25-qf6h","summary":"Duplicate Advisory: phpseclib: guardrails needed on isPrime and randomPrime","details":"### Duplicate Advisory\nThis advisory has been withdrawn because it is a duplicate of GHSA-2528-jw5q-ww88.

An attacker can construct a malformed certificate containing an extremely large prime to cause a denial of service (CPU consumption for an isPrime primality check).
