Dropbox: Significant Two step verification Authentication Bypass

This report described a concern with our “Trust this Computer” feature in Dropbox web sign in. The way our “Trust this Computer” feature works, at a high level, is that while authenticating using 2FA, the user can request that this device be trusted in the future so they don’t have to use 2FA...

Malicious Package

text-qrcode package contains malicious code. The randomBytes method is overwritten with a function that generates a weak entropy of 3 bytes and subsequently hashed, which would allow an attacker to guess the random value in a short amount of time...

Entropy Backdoor

Overview All versions of text-qrcode contain malicious code that overwrites the randomBytes method for the crypto module with a function that generates weak entropy. Instead of generating 32 bytes, the infected randomBytes will generate 3 bytes of entropy and hash them, resulting in a 32 byte val...

Phabricator: TOTP Key is shorter than RFC 4226 recommended minimum

mongoose Observed Behavior: When creating a TOTP secret a 16 character base32 encoded string is presented to the user. Expected Behavior: I would expect a 32 character base32 secret to be presented. The RFC recommends 160 bits of entropy, which is 32 character x 5 bits per character in a base32...

Insufficient Entropy

Overview Versions of cryptiles from version 3.1.0 through 3.1.2, and versions 4.0.0 to version 4.1.1 are vulnerable to insufficient entropy. The randomDigits method generates digits that lack a perfect distribution over enough attempts. Recommendation Update to version 3.1.3 or 4.1.2 or later...

The vulnerability of the BIOS loader of the Hyper-V hardware virtualization platform for Windows operating systems allows a hacker to circumvent built-in security restrictions.

The vulnerability of the BIOS loader of Hyper-V hardware virtualization systems for Windows operating systems arises from the unstable provision of high entropy during loading. Exploiting this vulnerability allows a remote attacker to circumvent built-in security restrictions...

Microsoft Windows Hyper-V Security Bypass Vulnerability

Microsoft Windows 10 and others are a series of operating systems released by Microsoft Corporation USA.Windows Hyper-V is one of the virtualization products that supports the creation of virtual machines in Windows. A security feature bypass vulnerability exists in Microsoft Windows Hyper-V that...

Insufficient Entropy in cryptiles

Versions of cryptiles prior to 4.1.2 are vulnerable to Insufficient Entropy. The randomDigits method does not provide sufficient entropy and its generates digits that are not evenly distributed. Recommendation Upgrade to version 4.1.2. The package is deprecated and has been moved to @hapi/cryptil...

Windows Hyper-V Security Feature Bypass Vulnerability

A security feature bypass vulnerability exists when Windows Hyper-V BIOS loader fails to provide a high-entropy source. To exploit this vulnerability, an attacker would need to reboot a guest virtual machine numerous times until the vulnerability is triggered. The security update addresses the...

Network Time Protocol Vulnerabilities (Update B)

OVERVIEW This updated advisory is a follow-up to the updated advisory titled ICSA-14-353-01A Network Time Protocol Vulnerabilities that was published December 23, 2014, on the NCCIC/ICS-CERT web site. Google Security Team researchers Neel Mehta and Stephen Roettger have coordinated multiple...
