Mozilla Firefox ESR < 60.5.1

high Nessus Plugin ID 122194

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 60.5.1. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-05 advisory.

- A use-after-free vulnerability in the Skia library can occur when creating a path, leading to a potentially exploitable crash. (CVE-2018-18356)

- An integer overflow vulnerability in the Skia library can occur after specific transform operations, leading to a potentially exploitable crash. (CVE-2019-5785)

- A buffer overflow vulnerability in the Skia library can occur with Canvas 2D acceleration on macOS. This issue was addressed by disabling Canvas 2D acceleration in Firefox ESR. *Note: this does not affect other versions and platforms where Canvas 2D acceleration is already disabled by default.* (CVE-2018-18335)

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 60.5.1 or later.
