Summary

Details

By holding a reference to the eval() function from an about:blank window, a malicious webpage could have gained access to the InstallTrigger object which would allow them to prompt the user to install an extension. Combined with user confusion, this could result in an unintended or malicious extension being installed. This vulnerability affects Firefox < 80, Thunderbird < 78.2, Thunderbird < 68.12, Firefox ESR < 68.12, Firefox ESR < 78.2, and Firefox for Android < 80.

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)
