Authorization Bypass

putty is vulnerable to authorization bypass. The vulnerability exists through the potential recycling of random numbers used in cryptography...

Information Disclosure

OpenSSL is vulnerable to information disclosure. A rewritten random number generator RNG that was intended to include protection in the event of a fork system call in order to ensure that the parent and child processes did not share the same RNG state and was not being used in the default case...

Matt Blaze on OTP Radio Stations

Matt Blaze discusses also here an interesting mystery about a Cuban one-time-pad radio station, and a random number generator error that probably helped arrest a pair of Russian spies in the US...

ALEOS Random Number Reuse Vulnerability

ALEOS is an integrated development environment for building customized embedded M2M applications. A random number reuse vulnerability exists in the ACEView service in ALEOS versions prior to 4.13.0, 4.9.5, and 4.4.9, which can be exploited by an attacker to replay messages...

The Linux kernel through 5.7.11 allows remote attackers to make observations that help to obtain sensitive information about the internal state of the network RNG aka CID-f227e3ec3b5c. This is related to drivers/char/random.c and kernel/time/timer.c.

Linux kernel information disclosure vulnerability (CNVD-2020-44611)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A security vulnerability exists in Linux kernel 5.7.11 and earlier versions. A remote attacker could exploit the vulnerability to obtain sensitive information about th...

Medium: openssl11

Issue Overview: In situations where an attacker receives automated notification of the success or failure of a decryption attempt an attacker, after sending a very large number of messages to be decrypted, can recover a CMS/PKCS7 transported encryption key or decrypt any RSA encrypted message tha...

Special Register Buffer speculative side channel

ISSUE DESCRIPTION This issue is related to the MDS and TAA vulnerabilities. Please see https://xenbits.xen.org/xsa/advisory-297.html MDS and https://xenbits.xen.org/xsa/advisory-305.html TAA for details. Certain processor operations microarchitecturally need to read data from outside the physical...

Unspecified Vulnerability in Elastic Cloud on Kubernetes

Elasticsearch is a set of Dutch Elasticsearch company built on Lucene open source distributed RESTful search engine . The product is mainly used in cloud computing and supports data indexing via HTTP using JSON. Elastic Cloud on Kubernetes version 1.1.0 before the existence of a security...

CVE-2020-7010

Elastic Cloud on Kubernetes ECK versions prior to 1.1.0 generate passwords using a weak random number generator. If an attacker is able to determine when the current Elastic Stack cluster was deployed they may be able to more easily brute force the Elasticsearch credentials generated by ECK...

USN-4376-1 openssl vulnerabilities

Cesar Pereida García, Sohaib ul Hassan, Nicola Tuveri, Iaroslav Gridin, Alejandro Cabrera Aldaya, and Billy Brumley discovered that OpenSSL incorrectly handled ECDSA signatures. An attacker could possibly use this issue to perform a timing side-channel attack and recover private ECDSA keys...

gcc: POWER9 "DARN" RNG intrinsic produces repeated output

The POWER9 backend in GNU Compiler Collection GCC before version 10 could optimize multiple calls of the builtindarn intrinsic into a single call, thus reducing the entropy of the random number generator. This occurred because a volatile operation was not specified. For example, within a single...
