Ubuntu Security Notice USN-3416-1
September 14, 2017

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

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

- Ubuntu 17.04
- 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 bypass same-origin
restrictions, bypass CSP restrictions, obtain sensitive information, spoof
the origin of modal alerts, cause a denial of service via application
crash, or execute arbitrary code. (CVE-2017-7753, CVE-2017-7779,
CVE-2017-7784, CVE-2017-7785, CVE-2017-7787, CVE-2017-7791, CVE-2017-7792,
CVE-2017-7800, CVE-2017-7801, CVE-2017-7802, CVE-2017-7803, CVE-2017-7807,
CVE-2017-7809)

A buffer overflow was discovered when displaying SVG content in some
circumstances. If a user were tricked in to opening a specially crafted
message, an attacker could potentially exploit this to cause a denial of
service via application crash, or execute arbitrary code. (CVE-2017-7786)

Update instructions:

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

Ubuntu 17.04:
  thunderbird                     1:52.3.0+build1-0ubuntu0.17.04.1

Ubuntu 16.04 LTS:
  thunderbird                     1:52.3.0+build1-0ubuntu0.16.04.1

Ubuntu 14.04 LTS:
  thunderbird                     1:52.3.0+build1-0ubuntu0.14.04.1

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