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 60.5. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-02 advisory.- A use-after-free vulnerability can occur while parsing an HTML5 stream in concert with custom HTML elements.
This results in the stream parser object being freed while still in use, leading to a potentially exploitable crash. (CVE-2018-18500)
- An earlier fix for an Inter-process Communication (IPC) vulnerability, CVE-2011-3079, added authentication to communication between IPC endpoints and server parents during IPC process creation. This authentication is insufficient for channels created after the IPC process is started, leading to the authentication not being correctly applied to later channels. This could allow for a sandbox escape through IPC channels due to lack of message validation in the listener process.
(CVE-2018-18505)
- Mozilla developers and community members Alex Gaynor, Christoph Diehl, Steven Crane, Jason Kratzer, Gary Kwong, and Christian Holler reported memory safety bugs present in Firefox 64 and Firefox ESR 60.4. Some of 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-2018-18501)
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 60.5 or later.See Also
