Ubuntu Security Notice 5131-1 - 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. 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. Various other issues were also addressed.

Software Description:

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

exploit this to steal authentication tokens.

package versions:
