### 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. ### Resources https://github.com/phpseclib/phpseclib/commit/ad5dbdf2129f5e0fb644637770b7f33de8ca8575 https://www.usenix.org/system/files/conference/usenixsecurity25/sec25cycle1-prepub-599-shi-bing.pdf
