Mozilla Thunderbird < 31.2 Multiple Vulnerabilities (Mac OS X)

High Nessus Plugin ID 78471


The remote Mac OS X host contains a mail client that is affected by multiple vulnerabilities.


The version of Thunderbird installed on the remote host is a version prior to 31.2. It is, therefore, affected by the following vulnerabilities :

- Multiple memory safety flaws exist within the browser engine. Exploiting these, an attacker can cause a denial of service or execute arbitrary code. (CVE-2014-1574, CVE-2014-1575)

- A buffer overflow vulnerability exists when capitalization style changes occur during CSS parsing.

- An out-of-bounds read error exists in the Web Audio component when invalid values are used in custom waveforms that leads to a denial of service or information disclosure. (CVE-2014-1577)

- An out-of-bounds write error exists when processing invalid tile sizes in 'WebM' format videos that result in arbitrary code execution. (CVE-2014-1578)

- A use-after-free error exists in the 'DirectionalityUtils' component when text direction is used in the text layout that results in arbitrary code execution. (CVE-2014-1581)

- Multiple issues exist in WebRTC when the session is running within an 'iframe' element that will allow the session to be accessible even when sharing is stopped and when returning to the website. This could lead to video inadvertently being shared. (CVE-2014-1585, CVE-2014-1586)


Upgrade to Thunderbird 31.2 or later.
