Ubuntu USN-1551-1 introduced regressions in Thunderbird.
==========================================================================
Ubuntu Security Notice USN-1551-2
September 28, 2012

thunderbird regressions
==========================================================================

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

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS

Summary:

USN-1551-1 introduced regressions in Thunderbird.

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

Details:

USN-1551-1 fixed vulnerabilities in Thunderbird. The new package caused a
regression in the message editor and certain performance regressions as
well. This update fixes the problems.

Original advisory details:

 Gary Kwong, Christian Holler, Jesse Ruderman, Steve Fink, Bob Clary, Andrew
 Sutherland, Jason Smith, John Schoenick, Vladimir Vukicevic and Daniel
 Holbert discovered memory safety issues affecting Thunderbird. If the user
 were tricked into opening a specially crafted E-Mail, an attacker could
 exploit these to cause a denial of service via application crash, or
 potentially execute code with the privileges of the user invoking
 Thunderbird. (CVE-2012-1970, CVE-2012-1971)
 
 Abhishek Arya discovered multiple use-after-free vulnerabilities. If the
 user were tricked into opening a specially crafted E-Mail, an attacker
 could exploit these to cause a denial of service via application crash, or
 potentially execute code with the privileges of the user invoking
 Thunderbird. (CVE-2012-1972, CVE-2012-1973, CVE-2012-1974, CVE-2012-1975,
 CVE-2012-1976, CVE-2012-3956, CVE-2012-3957, CVE-2012-3958, CVE-2012-3959,
 CVE-2012-3960, CVE-2012-3961, CVE-2012-3962, CVE-2012-3963, CVE-2012-3964)
 
 Mariusz Mlynsk discovered that it is possible to shadow the location object
 using Object.defineProperty. This could potentially result in a cross-site
 scripting (XSS) attack against plugins. With cross-site scripting
 vulnerabilities, if a user were tricked into viewing a specially crafted
 E-Mail, a remote attacker could exploit this to modify the contents or
 steal confidential data within the same domain. (CVE-2012-1956)
 
 Frédéric Hoguin discovered that bitmap format images with a negative height
 could potentially result in memory corruption. If the user were tricked
 into opening a specially crafted image, an attacker could exploit this to
 cause a denial of service via application crash, or potentially execute
 code with the privileges of the user invoking Thunderbird. (CVE-2012-3966)
 
 It was discovered that Thunderbird's WebGL implementation was vulnerable to
 multiple memory safety issues. If the user were tricked into opening a
 specially crafted E-Mail, an attacker could exploit these to cause a denial
 of service via application crash, or potentially execute code with the
 privileges of the user invoking Thunderbird. (CVE-2012-3967, CVE-2012-3968)
 
 Arthur Gerkis discovered multiple memory safety issues in Thunderbird's
 Scalable Vector Graphics (SVG) implementation. If the user were tricked
 into opening a specially crafted image, an attacker could exploit these to
 cause a denial of service via application crash, or potentially execute
 code with the privileges of the user invoking Thunderbird. (CVE-2012-3969,
 CVE-2012-3970)
 
 Christoph Diehl discovered multiple memory safety issues in the bundled
 Graphite 2 library. If the user were tricked into opening a specially
 crafted E-Mail, an attacker could exploit these to cause a denial of
 service via application crash, or potentially execute code with the
 privileges of the user invoking Thunderbird. (CVE-2012-3971)
 
 Nicolas Grégoire discovered an out-of-bounds read in the format-number
 feature of XSLT. This could potentially cause inaccurate formatting of
 numbers and information leakage. (CVE-2012-3972)
 
 It was discovered that when the DOMParser is used to parse text/html data
 in a Thunderbird extension, linked resources within this HTML data will be
 loaded. If the data being parsed in the extension is untrusted, it could
 lead to information leakage and potentially be combined with other attacks
 to become exploitable. (CVE-2012-3975)
 
 It was discovered that, in some instances, certain security checks in the
 location object could be bypassed. This could allow for the loading of
 restricted content and can potentially be combined with other issues to
 become exploitable. (CVE-2012-3978)
 
 Colby Russell discovered that eval in the web console can execute injected
 code with chrome privileges, leading to the running of malicious code in a
 privileged context. If the user were tricked into opening a specially
 crafted E-Mail, an attacker could exploit this to cause a denial of service
 via application crash, or potentially execute code with the privileges of
 the user invoking Thunderbird. (CVE-2012-3980)

Update instructions:

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

Ubuntu 12.04 LTS:
  thunderbird                     15.0.1+build1-0ubuntu0.12.04.1
  thunderbird-globalmenu          15.0.1+build1-0ubuntu0.12.04.1

Ubuntu 11.10:
  thunderbird                     15.0.1+build1-0ubuntu0.11.10.1
  thunderbird-globalmenu          15.0.1+build1-0ubuntu0.11.10.1

Ubuntu 11.04:
  thunderbird                     15.0.1+build1-0ubuntu0.11.04.1
  thunderbird-globalmenu          15.0.1+build1-0ubuntu0.11.04.1

Ubuntu 10.04 LTS:
  thunderbird                     15.0.1+build1-0ubuntu0.10.04.1

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