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

- Ubuntu 14.10
- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in Thunderbird.

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

Details:

Gary Kwong, Randell Jesup, Nils Ohlmeier, Jesse Ruderman, and Max Jonas
Werner discovered multiple memory safety issues in Thunderbird. If a user
were tricked in to opening a specially crafted message with scripting
enabled, an attacker could potentially exploit these to cause a denial of
service via application crash, or execute arbitrary code with the
privileges of the user invoking Thunderbird. (CVE-2014-1587)

Joe Vennix discovered a crash when using XMLHttpRequest in some
circumstances. If a user were tricked in to opening a specially crafted
message with scripting enabled, an attacker could potentially exploit this
to cause a denial of service. (CVE-2014-1590)

Berend-Jan Wever discovered a use-after-free during HTML parsing. If a
user were tricked in to opening a specially crafted message with scripting
enabled, an attacker could potentially exploit this to cause a denial of
service via application crash or execute arbitrary code with the
privileges of the user invoking Thunderbird. (CVE-2014-1592)

Abhishek Arya discovered a buffer overflow when parsing media content. If
a user were tricked in to opening a specially crafted message with
scripting enabled, an attacker could potentially exploit this to cause a
denial of service via application crash or execute arbitrary code with the
privileges of the user invoking Thunderbird. (CVE-2014-1593)

Byoungyoung Lee, Chengyu Song, and Taesoo Kim discovered a bad cast in the
compositor. If a user were tricked in to opening a specially crafted
message, an attacker could potentially exploit this to cause undefined
behaviour, a denial of service via application crash or execute abitrary
code with the privileges of the user invoking Thunderbird. (CVE-2014-1594)

Update instructions:

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

  thunderbird                     1:31.3.0+build1-0ubuntu0.14.10.1

Ubuntu 14.04 LTS:
  thunderbird                     1:31.3.0+build1-0ubuntu0.14.04.1

Ubuntu 12.04 LTS:
  thunderbird                     1:31.3.0+build1-0ubuntu0.12.04.1

all the necessary changes.
