Security Vulnerabilities fixed in Firefox 80 — Mozilla

If Firefox is installed to a user-writable directory, the Mozilla Maintenance Service would execute updater.exe from the install location with administrative privileges. Although the Mozilla Maintenance Service does ensure that updater.exe is signed by Mozilla, the version could have been rolled...

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...

MGASA-2020-0318 Updated firefox packages fix security vulnerability

WebRTC used the memory address of a class instance as a connection identifier. Unfortunately, this value is often transmitted to the peer, which allows bypassing ASLR CVE-2020-6514. Crafted media files could lead to a race in texture caches, resulting in a use-after-free in ANGLE...

FreeBSD : security/py-ecdsa -- multiple issues (a23ebf36-e8b6-4665-b0f3-4c977f9a145c)

py-ecdsa developers report : Fix CVE-2019-14853 - possible DoS caused by malformed signature decoding. Fix CVE-2019-14859 - signature malleability caused by insufficient checks of DER encoding C Tenable Network Security, Inc. The descriptive text and package checks in this plugin were extracted...

CVE-2020-17478

The CVE-2020-17478 entry affects Crypt::Perl, specifically ECDSA/EC/Point.pm before version 0.33, where timing-attack considerations in the EC point multiplication are not properly handled. The issue is documented across multiple sources (e.g., NVD/NVDB) with the root cause described as inadequat...

Security Bulletin: IBM Event Streams affected by multiple vulnerabilities in OpenSSL package

Summary IBM Event Streams affected by vulnerabilities in OpenSSL package Vulnerability Details CVEID: CVE-2019-1547 DESCRIPTION: OpenSSL could allow a local authenticated attacker to obtain sensitive information, caused by the ability to construct an EC group missing the cofactor using explicit...

Side Channel Attack

nss is vulnerable to side channel attack. It is possible because of a flaw in ECDSA signature generation...

Information Disclosure

Arm Mbed TLS is vulnerable to Information Disclosure. An attacker that can get precise enough side-channel measurements can recover the long-term ECDSA private key by 1 reconstructing the projective coordinate of the result of scalar multiplication by exploiting side channels in the conversion to...

Sensitive Information Disclosure

Arm Mbed TLS is vulnerable to sensitive information leakage. When deterministic ECDSA is enabled, it uses an RNG with insufficient entropy for blinding, which might allow an attacker to recover a private key via side-channel attacks if a victim signs the same message many times...

Information Disclosure

nss is vulnerable to information disclosure. An attacker is able to extract the position of zero and non-zero wNAF digits while nss-certutil tool performs scalar multiplication during the ECDSA signature generation when using the EM side-channel. With the partial information of the ECDSA nonce an...

Information Disclosure

mbedtls is vulnerable to information disclosure. The vulnerability exists as the ECDSA signature implementation in ecdsa.c in Arm Mbed Crypto 2.1 and Mbed TLS through 2.19.1 does not reduce the blinded scalar before computing the inverse, which allows a local attacker to recover the private key v...

CVE-2020-12401

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

A flaw was found in nss. Using the EM side-channel, it is possible to extract the position of zero and non-zero wNAF digits while nss-certutil tool performs scalar multiplication during the ECDSA signature generation, leaking partial information about the ECDSA nonce. Given a small number of ECDS...

CVE-2020-6829

A flaw was found in nss. Using the EM side-channel, it is possible to extract the position of zero and non-zero wNAF digits while nss-certutil tool performs scalar multiplication during the ECDSA signature generation, leaking partial information about the ECDSA nonce. Given a small number of ECDS...
