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-2023-4047,
 CVE-2023-4048, CVE-2023-4049, CVE-2023-4051, CVE-2023-4053, CVE-2023-4055,
 CVE-2023-4056, CVE-2023-4057, CVE-2023-4058)

 Max Vlasov discovered that Firefox Offscreen Canvas did not properly track
 cross-origin tainting. An attacker could potentially exploit this issue to
 access image data from another site in violation of same-origin policy.
 (CVE-2023-4045)

 Alexander Guryanov discovered that Firefox did not properly update the
 value of a global variable in WASM JIT analysis in some circumstances. An
 attacker could potentially exploit this issue to cause a denial of service.
 (CVE-2023-4046)

 Mark Brand discovered that Firefox did not properly validate the size of
 an untrusted input stream. An attacker could potentially exploit this issue
 to cause a denial of service. (CVE-2023-4050)");
