USN-3997-1: Thunderbird vulnerabilities
28 May 2019

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

  o Ubuntu 19.04
  o Ubuntu 18.10
  o Ubuntu 18.04 LTS
  o Ubuntu 16.04 LTS

Summary

Several security issues were fixed in Thunderbird.

Software Description

  o thunderbird - Mozilla Open Source mail and newsgroup client

Details

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, bypass
same-origin protections, or execute arbitrary code. (CVE-2019-18511,
CVE-2019-11691, CVE-2019-11692, CVE-2019-11693, CVE-2019-9797, CVE-2019-9800,
CVE-2019-9817, CVE-2019-9819, CVE-2019-9820)

Multiple security issues were discovered in Thunderbird. If a user were tricked
in to opening a specially crafted message, an attacker could potentially
exploit these to cause a denial of service, or execute arbitrary code.
(CVE-2019-5798, CVE-2019-7317)

A type confusion bug was discovered with object groups and UnboxedObjects. If a
user were tricked in to opening a specially crafted website in a browsing
context after enabling the UnboxedObjects feature, an attacker could
potentially exploit this to bypass security checks. (CVE-2019-9816)

It was discovered that history data could be exposed via drag and drop of
hyperlinks to and from bookmarks. If a user were tricked in to dragging a
specially crafted hyperlink to a bookmark toolbar or sidebar, and subsequently
back in to the web content area, an attacker could potentially exploit this to
obtain sensitive information. (CVE-2019-11698)
