Ubuntu Security Notice USN-4064-1
July 17, 2019

thunderbird vulnerabilities
==========================================================================

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

- Ubuntu 19.04
- Ubuntu 18.10
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in Thunderbird.

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

Details:

A sandbox escape was discovered in Thunderbird. If a user were tricked in to
installing a malicious language pack, an attacker could exploit this to
gain additional privileges. (CVE-2019-9811)

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 restrictions, conduct cross-site scripting (XSS)
attacks, spoof origin attributes, or execute arbitrary code.
(CVE-2019-11709, CVE-2019-11711, CVE-2019-11712, CVE-2019-11713,
CVE-2019-11715, CVE-2019-11717)

It was discovered that NSS incorrectly handled importing certain
curve25519 private keys. An attacker could exploit this issue to cause
Thunderbird to crash, resulting in a denial of service, or possibly
obtain sensitive information. (CVE-2019-11719)

It was discovered that NSS incorrectly handled certain p256-ECDH public
keys. An attacker could possibly exploit this issue to cause Thunderbird
to crash, resulting in a denial of service. (CVE-2019-11729)

It was discovered that Thunderbird treats all files in a directory as same
origin. If a user were tricked in to downloading a specially crafted HTML
file, an attacker could potentially exploit this to obtain sensitive
information from local files. (CVE-2019-11730)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 19.04:
thunderbird 1:60.8.0+build1-0ubuntu0.19.04.1

Ubuntu 18.10:
thunderbird 1:60.8.0+build1-0ubuntu0.18.10.1

Ubuntu 18.04 LTS:
thunderbird 1:60.8.0+build1-0ubuntu0.18.04.1

Ubuntu 16.04 LTS:
thunderbird 1:60.8.0+build1-0ubuntu0.16.04.2

After a standard system update you need to restart Thunderbird to make
all the necessary changes.
