Ruby on Rails: The authenticity_token can be reversed and used to forge valid per_form_csrf_tokens for arbitrary routes

When performcsrftokens is set to true, each form should protected against CSRF with a unique token that is not predictable by an attacker. Theperformcsrftoken is generated using a HMAC SHA-256 using a key that is exposed in a reversed authenticitytoken. The authenticitytoken is a Base64 encoding ...

Mozilla: Stack buffer overflow in HKDF output

A flaw was discovered in both Firefox and Thunderbird where 4 bytes of a HMAC output could be written past the end of a buffer stored on the memory stack. This could allow an attacker to execute arbitrary code or lead to a crash. This flaw can be exploited over the network...

CVE-2016-6302

An integer underflow flaw leading to a buffer over-read was found in the way OpenSSL parsed TLS session tickets. A remote attacker could use this flaw to crash a TLS server using OpenSSL if it used SHA-512 as HMAC for session tickets...

Timing attack on HMAC signature comparison in Apache Tapestry

The code which checks HMAC in form submissions used String.equals for comparisons, which results in a timing side channel for the comparison of the HMAC signatures. This could lead to remote code execution if an attacker is able to determine the correct signature for their payload. The comparison...

CVE-2019-10071

CVE-2019-10071 is an Apache Tapestry timing-attack vulnerability caused by using String.equals() to compare HMACs in form submissions. This creates a timing side channel that could let an attacker estimate the correct signature for a payload, potentially enabling remote code execution. Affected v...

Deserialization of untrusted data

Manipulating classpath asset file URLs, an attacker could guess the path to a known file in the classpath and have it downloaded. If the attacker found the file with the value of the tapestry.hmac-passphrase configuration symbol, most probably the webapp's AppModule class, the value of this symbo...

CVE-2019-16143

An issue was discovered in the blake2 crate before 0.8.1 for Rust. The BLAKE2b and BLAKE2s algorithms, when used with HMAC, produce incorrect results because the block sizes are half of the required sizes...

CVE-2019-16143

The CVE concerns the blake2 crate for Rust, affecting versions before 0.8.1. The root cause is incorrect block sizes when BLAKE2b/BLAKE2s are used with HMAC, causing MAC results to be computed with half the required sizes. Documents consistently describe miscalculation of MAC results (MacResult) ...
