Observable timing discrepancy allows determining username validity

In Jenkins 2.355 and earlier, LTS 2.332.3 and earlier, an observable timing discrepancy on the login form allows distinguishing between login attempts with an invalid username, and login attempts with a valid username and wrong password, when using the Jenkins user database security realm. This...

Hertzbleed exposes computers’ secret whispers

Hertzbleed is the name for a vulnerability that can be used to obtain cryptographic keys and other secret data from Intel and AMD CPUs, remotely. It works by monitoring changes in power consumption, which can be deduced by the careful timing of known workloads, thanks to a processor power saving...

Mozilla: Querying a WebAuthn token with a large number of allowCredential entries may have leaked cross-origin information

A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue as an attacker could have exploited a timing attack by sending a large number of allowCredential entries and detecting the difference between invalid key handles and cross-origin key handles. This could have...
