Mozilla Firefox < 70.0

critical Nessus Plugin ID 130169

Synopsis

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

Description

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 70.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-34 advisory.

- Mozilla developers and community members Bob Clary, Jason Kratzer, Aaron Klotz, Iain Ireland, Tyson Smith, Christian Holler, Steve Fink, Honza Bambas, Byron Campen, and Cristian Brindusan reported memory safety bugs present in Firefox 69 and Firefox ESR 68.1. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could be exploited to run arbitrary code.
(CVE-2019-11764)

- A compromised child process could have injected XBL Bindings into privileged CSS rules, resulting in arbitrary code execution and a sandbox escape. (CVE-2019-25136)

- Incorrect derivation of a packet length in WebRTC caused heap corruption via a crafted video file. This resulted in a potentially exploitable crash. (CVE-2018-6156)

- In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early. A subsequent call to <code>XMLGetCurrentLineNumber</code> or <code>XMLGetCurrentColumnNumber</code> then resulted in a heap-based buffer over-read. (CVE-2019-15903)

- When storing a value in IndexedDB, the value's prototype chain is followed and 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)

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 Firefox version 70.0 or later.
