Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in Thunderbird.

Software Description: - thunderbird: Mozilla Open Source mail and newsgroup client

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)
