Summary: thunderbird vulnerabilities

Details: 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)
