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-2024-7518,
CVE-2024-7521, CVE-2024-7524, CVE-2024-7526, CVE-2024-7527, CVE-2024-7528,
CVE-2024-7529, CVE-2024-7530, CVE-2024-7531)

It was discovered that Firefox did not properly manage certain memory
operations when processing graphics shared memory. An attacker could
potentially exploit this issue to escape the sandbox. (CVE-2024-7519)

Nan Wang discovered that Firefox did not properly handle type check in
WebAssembly. An attacker could potentially exploit this issue to execute
arbitrary code. (CVE-2024-7520)

Irvan Kurniawan discovered that Firefox did not properly check an attribute
value in the editor component, leading to an out-of-bounds read
vulnerability. An attacker could possibly use this issue to cause a denial
of service or expose sensitive information. (CVE-2024-7522)

Rob Wu discovered that Firefox did not properly check permissions when
creating a StreamFilter. An attacker could possibly use this issue to
modify response body of requests on any site using a web extension.
