Information Leakage

The libgcrypt library is vulnerable to information leakage. The vulnerability exists because of a flaw in the libgcrypt PRNG Pseudo-Random Number Generator, leaking the first 580 bytes of the PRNG output which allows the attacker to guess the following 20 bytes...

Cryptographically Weak PRNG

Overview Affected versions of generate-password generate random values that are biased towards certain characters depending on the chosen character sets. This may result in guessable passwords. Recommendation Update to version 1.4.1 or later. References - GitHub Pull - GitHub Advisory...

Cryptographically Weak Pseudo-Random Number Generator (PRNG) in akka-actor

Lightbend Akka 2.5.x before 2.5.16 allows message disclosure and modification because of an RNG error. A random number generator is used in Akka Remoting for TLS both classic and Artery Remoting. Akka allows configuration of custom random number generators. For historical reasons, Akka included t...

OrientDB Server Community Edition uses insufficiently random values to generate session IDs

OrientDB Server Community Edition before 2.0.15 and 2.1.x before 2.1.1 improperly relies on the java.util.Random class for generation of random Session ID values in the server/network/protocol/http/OHttpSessionManager.java, which makes it easier for remote attackers to predict a value by...

Cryptographically Weak PRNG in randomatic

Affected versions of randomatic generate random values using a cryptographically weak psuedo-random number generator. This may result in predictable values instead of random values as intended. Recommendation Update to version 3.0.0 or later...

Plone and Zope2 do not reseed pseudo-random number generator

Zope before 2.13.19, as used in Plone before 4.2.3 and 4.3 before beta 1, does not reseed the pseudo-random number generator PRNG, which makes it easier for remote attackers to guess the value via unspecified vectors. NOTE: this issue was SPLIT from CVE-2012-5508 due to different vulnerability...

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...

CVE-2018-12520

An issue was discovered in ntopng 3.4 before 3.4.180617. The PRNG involved in the generation of session IDs is not seeded at program startup. This results in deterministic session IDs being allocated for active user sessions. An attacker with foreknowledge of the operating system and standard...
