Ubuntu Security Notice USN-3436-1
October 11, 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-like
context, an attacker could potentially exploit these to read uninitialized
memory, bypass phishing and malware protection, conduct cross-site
scripting (XSS) attacks, cause a denial of service via application crash,
or execute arbitrary code. (CVE-2017-7793, CVE-2017-7810, CVE-2017-7814,
CVE-2017-7818, CVE-2017-7819, CVE-2017-7823, CVE-2017-7824)

Martin Thomson discovered that NSS incorrectly generated handshake hashes.
A remote attacker could potentially exploit this to cause a denial of
service via application crash, or execute arbitrary code. (CVE-2017-7805)

Update instructions:

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

Ubuntu 17.04:
  thunderbird                     1:52.4.0+build1-0ubuntu0.17.04.2

Ubuntu 16.04 LTS:
  thunderbird                     1:52.4.0+build1-0ubuntu0.16.04.2

Ubuntu 14.04 LTS:
  thunderbird                     1:52.4.0+build1-0ubuntu0.14.04.2

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