CVE-2023-4421

The NSS code used for checking PKCS1 v1.5 was leaking information useful in mounting Bleichenbacher-like attacks. Both the overall correctness of the padding as well as the length of the encrypted message was leaking through timing side-channel. By sending large number of attacker-selected...

The sound of you typing on your keyboard could reveal your password

As if password authentications coffin needed any more nails, researchers in the UK have discovered yet another way to hammer one in. The technique, developed at Durham University, the University of Surrey, and Royal Holloway University of London, builds on previous work to produce a more accurate...

CVE-2023-45287

A flaw was found in the Golang crypto/tls standard library. In previous versions, the package was vulnerable to a Timing Side Channel attack by observing the time it took for RSA-based TLS key exchanges, which was not constant. This flaw allows a malicious user to gather information from the...

Google Android elevation of privilege vulnerability (CNVD-2024-07127)

Google Android is a Linux-based open source operating system from Google. Google Android suffers from an elevation of privilege vulnerability due to the disclosure of side-channel information in the BTMble.cc script BTMBleVerifySignature, which can be exploited by an attacker to gain elevated...

AZL-79088 CVE-2023-45287 affecting package golang 1.26.5-2

Before Go 1.20, the RSA based TLS key exchanges used the math/big library, which is not constant time. RSA blinding was applied to prevent timing attacks, but analysis shows this may not have been fully effective. In particular it appears as if the removal of PKCS1 padding may leak timing...
