performing RSA decryption. A remote attacker could possibly use this
issue to recover sensitive information. (CVE-2023-5388)
It was discovered that Firefox did not properly handle WASM register
values in some circumstances. An attacker could potentially exploit this
issue to cause a denial of service. (CVE-2024-2606)
Gary Kwong discovered that Firefox incorrectly updated return registers
for JIT code on Armv7-A systems. An attacker could potentially exploit
this issue to execute arbitrary code. (CVE-2024-2607)

character encoding. An attacker could potentially exploit this issue to
cause a denial of service. (CVE-2024-2608)

SafeRefPtr. An attacker could potentially exploit this issue to cause a
denial of service, or execute arbitrary code. (CVE-2024-2612)

decoding. A attacker could potentially exploit this issue to cause a
denial of service. (CVE-2024-2613)
