Details
Multiple security issues were discovered in Firefox. If a user were
tricked into opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, bypass security
restrictions, spoof the browser UI, confuse the user, conduct phishing
attacks, or execute arbitrary code. (CVE-2021-38503, CVE-2021-38504,
CVE-2021-38506, CVE-2021-38507, CVE-2021-38508, CVE-2021-38509)
It was discovered that the ‘Copy Image Link’ context menu action
would copy the final image URL after redirects. If a user were tricked
into copying and pasting a link for an embedded image that triggered
authentication flows back to the page, an attacker could potentially
exploit this to steal authentication tokens.
