Astra Linux - уязвимость в nss

When converting coordinates from projective to affine, the modular inversion was not performed in constant time, allowing for a timing-based side channel attack. This vulnerability affects Firefox versions less than 80, as well as Firefox for Android versions less than 80...

Linux Distros Unpatched Vulnerability : CVE-2019-19963

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - An issue was discovered in wolfSSL before 4.3.0 in a non-default configuration where DSA is enabled. DSA signing uses the BEEA algorithm during modular inversio...

Symbolic Generation and Modular Embedding of High-Quality Abc-Triples

We present a symbolic identity for generating integer triples $a, b, c$ satisfying $a + b = c$, inspired by structural features of the \emphabc conjecture. The construction uses powers of $2$ and $3$ in combination with modular inversion in $\mathbbZ/3^p\mathbbZ$, leading to a parametric identity...

CVE-2024-45678

Yubico YubiKey 5 Series devices with firmware before 5.7.0 and YubiHSM 2 devices with firmware before 2.4.0 allow an ECDSA secret-key extraction attack that requires physical access and expensive equipment in which an electromagnetic side channel is present because of a non-constant-time modular...

SUSE CVE-2020-12400

When converting coordinates from projective to affine, the modular inversion was not performed in constant time, resulting in a possible timing-based side channel attack. This vulnerability affects Firefox 80 and Firefox for Android 80...

nss: P-384 and P-521 implementation uses a side-channel vulnerable modular inversion function

A side-channel flaw was found in NSS, in the way P-384 and P-521 curves are used in the generation of EDSA signatures, leaking partial information about the ECDSA nonce. Given a small number of ECDSA signatures, this information can be used to steal the private key. The highest threat from this...
