phpseclib: guardrails needed on isPrime and randomPrime
Impact
Anyone trying to generate a prime and testing the primality of a number.
Patches
https://github.com/phpseclib/phpseclib/commit/ad5dbdf2129f5e0fb644637770b7f33de8ca8575
Workarounds
Using the GMP extension would probably help, assuming that one has its own guardrails.

An issue was discovered in phpseclib 1.x before 1.0.23, 2.x before 2.0.47, and 3.x before 3.0.36. 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). NOTE: this issue was introduced when attempting to fix CVE-2023-27560.
