GHSA-2528-JW5Q-WW88 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. Resources...

Denial Of Service (DoS)

phpseclib/phpseclib is vulnerable to a Denial Of Service DoS. The vulnerability is due to a flaw in handling malformed certificates in the phpseclib/Math/BigInteger.php file by using the method isPrime. It allows an attacker to trigger excessive CPU consumption during the isPrime primality check...
