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...

DEBIAN-CVE-2024-27354

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...

Design/Logic Flaw

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.

CVE-2024-27354

A vulnerability exists in phpseclib versions 1.x before 1.0.23, 2.x before 2.0.47, and 3.x before 3.0.36. The root cause is insufficient validation of user data within the isPrime() and randomPrime() functions, specifically when processing large numbers. An attacker can exploit this by constructi...
