CVE-2017-16541

Description

Firefox proxy settings can be bypassed by using the automount feature with autofs to create a mount point on the local file system. Content can be loaded from this mounted file system directly using a file: URI, bypassing configured proxy settings. This issue only affects OS X in default configuration; on Linux systems, autofs must also be installed for the vulnerability to occur.

Statement

This flaw cannot be exploited through email in Thunderbird as scripting is disabled in this for email content. It may be possible to exploit through Feeds (Atom or RSS) or other browser-like contexts.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
