Details

USN-6143-1 fixed vulnerabilities in Firefox. The update introduced
several minor regressions. This update fixes the problem.

We apologize for the inconvenience.

Original advisory 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, obtain sensitive
information across domains, or execute arbitrary code. (CVE-2023-34414,
CVE-2023-34416, CVE-2023-34417)

Jun Kokatsu discovered that Firefox did not properly validate site-isolated
process for a document loaded from a data: URL that was the result of a
redirect, leading to an open redirect attack. An attacker could possibly
use this issue to perform phishing attacks. (CVE-2023-34415)
