mailnews in Mozilla Thunderbird before 2.0.0.18 and SeaMonkey before 1.1.13, when JavaScript is enabled in mail, allows remote attackers to obtain sensitive information about the recipient, or comments in forwarded mail, via script that reads the (1) .documentURI or (2) .textContent DOM properties.

The remote host is affected by the vulnerability described in GLSA-201301-01 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox,       Thunderbird, SeaMonkey, NSS, GNU IceCat, and XULRunner. Please review the       CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to view a specially crafted web       page or email, possibly resulting in execution of arbitrary code or a       Denial of Service condition. Furthermore, a remote attacker may be able       to perform Man-in-the-Middle attacks, obtain sensitive information,       bypass restrictions and protection mechanisms, force file downloads,       conduct XML injection attacks, conduct XSS attacks, bypass the Same       Origin Policy, spoof URL&rsquo;s for phishing attacks, trigger a vertical       scroll, spoof the location bar, spoof an SSL indicator, modify the       browser&rsquo;s font, conduct clickjacking attacks, or have other unspecified       impact.
    A local attacker could gain escalated privileges, obtain sensitive       information, or replace an arbitrary downloaded file.
  Workaround :

    There is no known workaround at this time.

Versions of Mozilla Thunderbird prior to 2.0.0.18 are affected by the following vulnerabilities :

 - The canvas element can be used in conjunction with an HTTP redirect to bypass same-origin restrictions and gain access to the content in arbitrary images from other domains. (MFSA 2008-48)
 - By tampering with the 'window.__proto__' object, one can cause the browser to place a lock on a non-native object, leading to a crash and possible code execution. (MFSA 2008-50)
 - There are several stability bugs in the browser engine that may lead to crashes with evidence of memory corruption. (MFSA 2008-52)
 - Crashes and remote code execution in nsFrameManager are possible by modifying certain properties of a file input element before it has finished initializing. (MFSA 2008-55)
 - The same-origin check in 'nsXMLHttpRequest: : NotifyEventListeners()' can be bypassed. (MFSA 2008-56)
 - There is an error in the method used to parse the default namespace in an E4X document caused by quote characters in the namespace not being properly escaped. (MFSA 2008-58)
 - Scripts in a malicious mail message can access the .document URI and .textContext DOM properties. (MFSA 2008-59)

The installed version of Thunderbird is earlier than 2.0.0.18.  Such versions are potentially affected by the following security issues :

  - The canvas element can be used in conjunction with an     HTTP redirect to bypass same-origin restrictions and     gain access to the content in arbitrary images from     other domains. (MFSA 2008-48)

  - By tampering with the window.__proto__.__proto__ object,     one can cause the browser to place a lock on a non-     native object, leading to a crash and possible code     execution. (MFSA 2008-50)

  - There are several stability bugs in the browser engine     that could lead to crashes with evidence of memory     corruption. (MFSA 2008-52)

  - Crashes and remote code execution in nsFrameManager are     possible by modifying certain properties of a file     input element before it has finished initializing.
    (MFSA 2008-55)

  - The same-origin check in     'nsXMLHttpRequest::NotifyEventListeners()' can be     bypassed. (MFSA 2008-56)

  - There is an error in the method used to parse the     default namespace in an E4X document caused by quote     characters in the namespace not being properly escaped.
    (MFSA 2008-58)

  - Scripts in a malicous mail message can access the     .document URI and .textContext DOM properties.
    (MFSA 2008-59)

The installed version of SeaMonkey is earlier than 1.1.13.  Such versions are potentially affected by the following security issues :

  - Locally saved '.url' shortcut files can be used to read     information stored in the local cache. (MFSA 2008-47)

  - The canvas element can be used in conjunction with an     HTTP redirect to bypass same-origin restrictions and     gain access to the content in arbitrary images from     other domains. (MFSA 2008-48)

  - Arbitrary code execution is possible via Flash Player     dynamic module unloading. (MFSA 2008-49)

  - By tampering with the window.__proto__.__proto__ object,     one can cause the browser to place a lock on a non-     native object, leading to a crash and possible code     execution. (MFSA 2008-50)

  - There are several stability bugs in the browser engine     that may lead to crashes with evidence of memory     corruption. (MFSA 2008-52)

  - There is a buffer overflow that can be triggered by     sending a specially crafted 200 header line in the HTTP     index response. (MFSA 2008-54)

  - Crashes and remote code execution in nsFrameManager are     possible by modifying certain properties of a file     input element before it has finished initializing.
    (MFSA 2008-55)

  - The same-origin check in     'nsXMLHttpRequest::NotifyEventListeners()' can be     bypassed. (MFSA 2008-56)

  - The '-moz-binding' CSS property can be used to bypass     security checks which validate codebase principals.
    (MFSA 2008-57)

  - There is an error in the method used to parse the     default namespace in an E4X document caused by quote     characters in the namespace not being properly escaped.
    (MFSA 2008-58)

  - Scripts in a malicous mail message can access the     .document URI and .textContext. DOM properties.
