New! Plugin Severity Now Using CVSS v3

Synopsis

A web browser installed on the remote Windows host is affected by multiple vulnerabilities.

Description

The version of Firefox ESR installed on the remote Windows host is prior to 68.2. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-33 advisory, including the following:

- In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) could then result in a heap-based buffer over-read. (CVE-2019-15903)

- A use-after-free vulnerability exists in IndexedDB when creating updates. When following the value's prototype chain, it was possible to retain a reference to a locale, delete it, and subsequently reference it. This resulted in a use-after-free and a potentially exploitable crash. (CVE-2019-11757)

- A potential memory corruption vulnerability is present in the accessibility engine when 360 Total Security is installed, resulting in a potentially exploitable crash. (CVE-2019-11758)

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

Solution

Upgrade to Mozilla Firefox ESR version 68.2 or later.
