Summary

Details

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 vulnerability affects Firefox < 80 and Firefox for Android < 80.

Severity

5.3 (Medium)

Summary

firefox vulnerabilities

Details

Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, trick the user in to installing a malicious extension, spoof the URL bar, leak sensitive information between origins, or execute arbitrary code. (CVE-2020-15664, CVE-2020-15665, CVE-2020-15666, CVE-2020-15670)

It was discovered that NSS incorrectly handled certain signatures. An attacker could possibly use this issue to expose sensitive information. (CVE-2020-12400, CVE-2020-12401, CVE-2020-6829)

A data race was discovered when importing certificate information in to the trust store. An attacker could potentially exploit this to cause an unspecified impact. (CVE-2020-15668)
