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

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

- Ubuntu 18.04 LTS
- Ubuntu 17.10
- 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:

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 CORS restrictions, obtain sensitive information, or execute
arbitrary code. (CVE-2018-12359, CVE-2018-12360, CVE-2018-12362,
CVE-2018-12363, CVE-2018-12364, CVE-2018-12365, CVE-2018-12366)

It was discovered that S/MIME and PGP decryption oracles can be built with
HTML emails. An attacker could potentially exploit this to obtain
sensitive information. (CVE-2018-12372)

It was discovered that S/MIME plaintext can be leaked through HTML
reply/forward. An attacker could potentially exploit this to obtain
sensitive information. (CVE-2018-12373)

It was discovered that forms can be used to exfiltrate encrypted mail
parts by pressing enter in a form field. An attacker could potentially
exploit this to obtain sensitive information. (CVE-2018-12374)

Update instructions:

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

Ubuntu 18.04 LTS:
  thunderbird                     1:52.9.1+build3-0ubuntu0.18.04.1

Ubuntu 17.10:
  thunderbird                     1:52.9.1+build3-0ubuntu0.17.10.1

Ubuntu 16.04 LTS:
  thunderbird                     1:52.9.1+build3-0ubuntu0.16.04.1

Ubuntu 14.04 LTS:
  thunderbird                     1:52.9.1+build3-0ubuntu0.14.04.1

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