USN-2460-1: Thunderbird vulnerabilities

19 January 2015

Several security issues were fixed in Thunderbird.



  • thunderbird - Mozilla Open Source mail and newsgroup client


Christian Holler and Patrick McManus 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-2014-8634)

Muneaki Nishimura discovered that requests from navigator.sendBeacon()
lack an origin header. If a user were tricked in to opening a specially
crafted message with scripting enabled, an attacker could potentially
exploit this to conduct cross-site request forgery (XSRF) attacks.

Xiaofeng Zheng discovered that a web proxy returning a 407 response
could inject cookies in to the originally requested domain. If a user
connected to a malicious web proxy, an attacker could potentially exploit
this to conduct session-fixation attacks. (CVE-2014-8639)

Update instructions

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

Ubuntu 14.10
Ubuntu 14.04
Ubuntu 12.04

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