Firefox. The update introduced several minor regressions. This update fixes
the problem.

We apologize for the inconvenience.

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,

Alexander Guryanov discovered that Firefox did not properly update the
value of a global variable in WASM JIT analysis in some circumstances. An
