RSA1_5 (RSAES-PKCS1-v1_5) decryption lacks implicit rejection, exposing a Bleichenbacher/Marvin padding oracle

Impact RSACrypt::decryptWithRSA15 used by the RSA15 key-encryption algorithm implements RSAES-PKCS1-v15 decryption by inspecting the padding after RSADP and throwing InvalidArgumentException as soon as the padding is malformed. It does not implement the implicit-rejection countermeasure required ...

CVE-2024-34353

The matrix-sdk-crypto crate, part of the Matrix Rust SDK project, is an implementation of a Matrix end-to-end encryption state machine in Rust. In Matrix, the server-side key backup stores encrypted copies of Matrix message keys. This facilitates key sharing between a user's devices and provides ...

GHSA-9GGC-845V-GCGV matrix-sdk-crypto contains a log exposure of private key of the server-side key backup

Introduction In Matrix, the server-side key backup stores encrypted copies of Matrix message keys. This facilitates key sharing between a user's devices and provides a redundant copy in case all devices are lost. The key backup uses asymmetric cryptography, with each server-side key backup assign...

This update provides security bug fixes and minor enhancements. Limit the size of calculations performed by mbedtlsmpiexpmod to MBEDTLSMPIMAXSIZE to prevent a potential denial of service when generating Diffie-Hellman key pairs. A failure of the random generator was ignored in mbedtlsmpifillrando...

Is FIDO the future instrument to prove our identity?

FIDO, short for Fast IDentity Online, is an industry consortium started in 2013 to address the lack of interoperability among strong authentication devices and the problems users face creating and remembering multiple usernames and passwords. Among the founders were those who work in the financia...

JKS Private Key Cracker - Cracking passwords of private key entries in a JKS file

The Java Key Store JKS is the Java way of storing one or several cryptographic private and public keys for asymmetric cryptography in a file. While there are various key store formats, Java and Android still default to the JKS file format. JKS is one of the file formats for Java key stores, but J...
