Insecure Randomness

php is vulnerable to insecure randomness. The vulnerability as it was discovered that the PHP lcgvalue function used insufficient entropy to seed the pseudo-random number generator. A remote attacker could possibly use this flaw to predict values returned by the function, which are used to genera...

Weak Random Number Generator

php is vulnerable to weak random number generator. The vulnerability exists as it was discovered that PHP did not properly seed its pseudo-random number generator used by functions such as rand and mtrand, possibly allowing an attacker to easily predict the generated pseudo-random values...

Use of Cryptographically Weak Pseudo-Random Number Generator in org.pac4j:pac4j-saml

The SAML identifier generated within SAML2Utils.java was found to make use of the apache commons-lang3 RandomStringUtils class which makes them predictable due to RandomStringUtils PRNG's algorithm not being cryptographically strong. This issue only affects the 3.X release of pac4j-saml...

GHSA-54MG-VGRP-MWX9 Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) in Ratpack

Ratpack versions before 1.6.1 generate a session ID using a cryptographically weak PRNG in the JDK's ThreadLocalRandom. This means that if an attacker can determine a small window for the server start time and obtain a session ID value, they can theoretically determine the sequence of session IDs...

PHP 7.0.x < 7.0.1 Multiple Vulnerabilities

According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.1. It is, therefore, affected by multiple vulnerabilities : - A use-after-free error exists in the collatorsortwithsortkeys function due to improper clearing of pointers when destroying an array. An...

Attack on Pseudo-random number generator (PRNG) used in 1000 Guess, an Ethereum lottery game. (CVE-2018–12454)

Abstract An Ethereum lottery game, 1000 Guess, has a vulnerability that it generates random numbers predictable by anyone. This game decides a winner by a random number when the number of players who bet on the contract reaches to the predetermined number. The contract generates the random number...
