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...
The vulnerability of the `generate` function in the Werkzeug web application library, which allows an attacker to gain unauthorized access to confidential data.
The vulnerability of the generate function in the Werkzeug web application library’s init.py file is related to a lack of entropy in the PIN selection process. Exploiting this vulnerability could allow an attacker to gain unauthorized access to confidential data...
GHSA-265Q-28RP-CHQ5 Insecure Entropy Source - Math.random() in node-uuid
Affected versions of node-uuid consistently fall back to using Math.random as an entropy source instead of crypto, which may result in guessable UUID's. Recommendation Update to version 1.4.4 or later...

The vulnerability of the PRNG component of the FortiOS operating system allows a hacker to gain unauthorized access to protected information.
The vulnerability of the PRNG component in the FortiOS operating system relates to the use of a weak entropy source during key generation. Exploiting this vulnerability could allow an attacker, operating remotely, to gain unauthorized access to protected information, when FortiOS acts as a client...
CVE-2015-3006
On the QFX3500 and QFX3600 platforms, the number of bytes collected from the RANDOMINTERRUPT entropy source when the device boots up is insufficient, possibly leading to weak or duplicate SSH keys or self-signed SSL/TLS certificates. Entropy increases after the system has been up and running for...

CVE-2015-3006
CVE-2015-3006 applies to Juniper Junos OS on QFX3500 and QFX3600 switches. The described vulnerability is an entropy issue: during boot the device collects too few bytes from the RANDOM_INTERRUPT entropy source, which can lead to weak or duplicate SSH keys and self-signed SSL/TLS certificates. En...
CVE-2015-3006 Junos: QFX Series: Insufficient entropy on QFX3500 and QFX3600 platforms when the system boots up
On the QFX3500 and QFX3600 platforms, the number of bytes collected from the RANDOMINTERRUPT entropy source when the device boots up is insufficient, possibly leading to weak or duplicate SSH keys or self-signed SSL/TLS certificates. Entropy increases after the system has been up and running for...
New Research Paper: Prevalence and impact of low-entropy packing schemes in the malware ecosystem
Detection of malware is a constant battle between the technologies designed to detect and prevent malware and the authors creating them. One common technique adversaries leverage is packing binaries. Packing an executable is similar to applying compression or encryption and can inhibit the abilit...

The Linux CSPRNG Is Now Good!
Oceans of ink and hours on stage have been spent to convince the world that the best random number generator is /dev/urandom, the kernel one. And it is, and its always been. However, an uncomfortable truth was that the Linux CSPRNG really could have been better than it was. Userspace CSPRNGs...
