Mozilla Thunderbird < 45.7

critical Nessus Plugin ID 275665

Language:

Synopsis

A mail client installed on the remote macOS or Mac OS X host is affected by multiple vulnerabilities.

Description

The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 45.7. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2017-03 advisory.

 - A use-after-free vulnerability in the Media Decoder when working with media files when some events are fired after the media elements are freed from memory. (CVE-2017-5396)

 - JIT code allocation can allow for a bypass of ASLR and DEP protections leading to potential memory corruption attacks. (CVE-2017-5375)

 - Use-after-free while manipulating XSL in XSLT documents (CVE-2017-5376)

 - Hashed codes of JavaScript objects are shared between pages. This allows for pointer leaks because an objects address can be discovered through hash codes, and also allows for data leakage of an objects content using these hash codes. (CVE-2017-5378)

 - A potential use-after-free found through fuzzing during DOM manipulation of SVG content. (CVE-2017-5380)

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 45.7 or later.
