Summary
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)
