Mozilla Thunderbird < 52.7

Synopsis

A mail client installed on the remote Windows host is affected by multiple vulnerabilities.

Description

The version of Thunderbird installed on the remote Windows host is prior to 52.7. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2018-09 advisory.

- Mozilla developers Jet Villegas and Randell Jesup reported memory safety bugs present in Firefox ESR 52.6 and Thunderbird 52.6. These bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. (CVE-2018-5145)

- A buffer overflow can occur when manipulating the SVG <code>animatedPathSegList</code> through script.
This results in a potentially exploitable crash. (CVE-2018-5127)

- A lack of parameter validation on IPC messages results in a potential out-of-bounds write through malformed IPC messages. This can potentially allow for sandbox escape through memory corruption in the parent process. (CVE-2018-5129)

- An integer overflow can occur during conversion of text to some Unicode character sets due to an unchecked length parameter. (CVE-2018-5144)

- An out of bounds memory write while processing Vorbis audio data was reported through the Pwn2Own contest.
(CVE-2018-5146)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Mozilla Thunderbird version 52.7 or later.
