Two security issues were discovered in the JavaScript engine in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could exploit this by causing a denial of service, or executing arbitrary code.

It was discovered that Thunderbird allowed PAC files to specify that requests to localhost are sent through the proxy to another server. If proxy auto-detection is enabled, an attacker could potentially exploit this to conduct attacks on local services and tools. (CVE-2018-18506)

Multiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, or execute arbitrary code. (CVE-2019-9788, CVE-2019-9790, CVE-2019-9791, CVE-2019-9792, CVE-2019-9795, CVE-2019-9796, CVE-2019-9810, CVE-2019-9813)

A mechanism was discovered that removes some bounds checking for string, array, or typed array accesses if Spectre mitigations have been disabled. If a user were tricked in to opening a specially crafted website in a browsing context with Spectre mitigations disabled, an attacker could potentially exploit this to cause a denial of service, or execute arbitrary code. (CVE-2019-9793)
