Formal Verification of Probing Security Via Conditional Independence

Side-channel attacks are a major threat to the security of cryptosystems. Masking is a widely used countermeasure against such attacks, but proving the security of masked algorithms is error-prone without formal verification. In this work, we propose a novel approach to formal verification of...

Astra Linux – Vulnerability in CGal

There are multiple code execution vulnerabilities in the Nef polygon-parsing functionality of CGAL libcgal CGAL-5.1.1. A specially crafted malformed file can lead to an out-of-bounds read and type confusion, which could result in code execution. An attacker can provide malicious input to trigger...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: xfrm: Zero padding when dumping algorithms and encap templates. When copying data to user-space, we must ensure that only valid data is copied. Padding in structures may contain random potentially sensitive data and should never ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: crypto: tegra – Added the missing CRYPTOALGASYNC flag. The tegra crypto driver failed to set CRYPTOALGASYNC for its asynchronous algorithms. As a result, the crypto API would select these algorithms for users who request only...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: erofs: fixed an issue where the algorithm used for encoded extents was invalid. The current algorithm sanity checks do not properly apply to newly encoded extents. We need to unify the algorithm checks with the...

OpenSSH: OpenSSH: Information disclosure due to unintended cryptographic algorithm usage

A flaw was found in OpenSSH. This vulnerability allows the system to use unintended Elliptic Curve Digital Signature Algorithm ECDSA algorithms. This occurs because the configuration for accepted public key algorithms is misinterpreted, leading to the use of weaker cryptographic methods than...
