firefox vulnerabilities

Published Jan 30, 2019 · Updated Apr 22, 2026

Ecosystem: Ubuntu

Summary

Multiple security issues were discovered in Firefox. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, gain additional
privileges by escaping the sandbox, or execute arbitrary code.
(CVE-2018-18500, CVE-2018-18501, CVE-2018-18502, CVE-2018-18503,
CVE-2018-18504, CVE-2018-18505)

It was discovered that Firefox allowed PAC files to specify that requests
to localhost are sent through the proxy to another server. If proxy
auto-detection is enabled, an attacker could potentially exploit this to
conduct attacks on local services and tools. (CVE-2018-18506)
