CVE-2020-6829

When performing EC scalar point multiplication, the wNAF point multiplication algorithm was used; which leaked partial information about the nonce used during signature generation. Given an electro-magnetic trace of a few signature generations, the private key could have been computed. This...

CVE-2020-6829

CVE-2020-6829 is a vulnerability in NSS (Network Security Services) libraries (nss, nss-util, nss-softokn, nspr) where the wNAF scalar point multiplication during ECDSA signature generation leaks partial nonce information. This side-channel can enable an attacker with electromagnetic traces from ...

Design/Logic Flaw

During ECDSA signature generation, padding applied in the nonce designed to ensure constant-time scalar multiplication was removed, resulting in variable-time execution dependent on secret data. This vulnerability affects Firefox 80 and Firefox for Android 80...

CVE-2020-12401

CVE-2020-12401: In ECDSA signature generation, padding used to ensure constant-time scalar multiplication was removed, causing variable-time execution based on secret data. Affected: Firefox < 80 and Firefox for Android

KLA11942 Multiple vulnerabilities in Mozilla Firefox

Multiple vulnerabilities were found in Mozilla Firefox. Malicious users can exploit these vulnerabilities to obtain sensitive information, bypass security restrictions, cause denial of service, execute arbitrary code, gain privileges, spoof user interface. Below is a complete list of...

qemu: weak signature generation in Pointer Authentication support for ARM

A flaw was found in QEMU in the implementation of the Pointer Authentication PAuth support for ARM. A general failure of the signature generation process caused every PAuth-enforced pointer to be signed with the same signature. A local attacker could obtain the signature of a protected pointer an...

Design/Logic Flaw

A flaw was found in QEMU in the implementation of the Pointer Authentication PAuth support for ARM introduced in version 4.0 and fixed in version 5.0.0. A general failure of the signature generation process caused every PAuth-enforced pointer to be signed with the same signature. A local attacker...

CVE-2020-10702

CVE-2020-10702 affects QEMU’s ARM Pointer Authentication (PAuth) support. The flaw, introduced in 4.x and fixed in 5.0.0, causes the signature generation process to always sign PAuth-enforced pointers with the same signature. This enables a local attacker to obtain the signature of a protected po...

CVE-2020-12399

A flaw was found in the DSA signature generation function in nss. During the process of generating a DSA signature, the nonce value 'k' is not padded, exposing the bit length. Combined with other techniques, this can result in the recovery of the DSA private key. The highest threat from this...

RHEL 8 : openssl (RHSA-2019:3700)

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:3700 advisory. OpenSSL is a toolkit that implements the Secure Sockets Layer SSL and Transport Layer Security TLS protocols, as well as a full-strength...

CVE-2019-13627

A timing attack was found in the way ECCDSA was implemented in libgcrypt. A man-in-the-middle attacker could use this attack during signature generation to recover the private key. This attack is only feasible when the attacker is local to the machine where the signature is being generated. Attac...

CVE-2019-13629

MatrixSSL 4.2.1 and earlier contains a timing side channel in ECDSA signature generation. This allows a local or a remote attacker, able to measure the duration of hundreds to thousands of signing operations, to compute the private key used. The issue occurs because crypto/pubkey/eccmath.c scalar...

CVE-2019-13628

CVE-2019-13628 affects wolfSSL/wolfCrypt 4.0.0 and earlier when built without --enable-fpecc, --enable-sp, or --enable-sp-math. The issue is a timing side-channel in ECDSA signature generation caused by ecc.c scalar multiplication leaking bit-length information. This may allow a local attacker wh...

CVE-2019-13628

wolfSSL and wolfCrypt 4.0.0 and earlier when configured without --enable-fpecc, --enable-sp, or --enable-sp-math contain a timing side channel in ECDSA signature generation. This allows a local attacker, able to precisely measure the duration of signature operations, to infer information about th...
