6) Use-after-free (CVE-ID: CVE-2024-7528)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in IndexedDB. A remote attacker can trick the victim into visiting a specially crafted website, trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

7) Multiple Interpretations of UI Input (CVE-ID: CVE-2024-7529)

CWE-ID: CWE-450 - Multiple Interpretations of UI Input

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exist due to improper handling of the date picker, which can obscure security prompts. A remote attacker use a malicious site to trick a victim into granting permissions.

8) Use-after-free (CVE-ID: CVE-2024-7530)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a remote attacker to crash the browser

The vulnerability exists due to a use-after-free error in JavaScript code coverage collection. A remote attacker can trick the victim into visiting a specially crafted website, trigger a use-after-free error and crash the browser.

9) Cryptographic issues (CVE-ID: CVE-2024-7531)

CWE-ID: CWE-310 - Cryptographic Issues

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a remote attacker to gain access to sensitive information.

Calling PK11_Encrypt() in NSS using CKM_CHACHA20 and the same buffer for input and output can result in plaintext on an Intel Sandy Bridge processor. In Firefox this only affects the QUIC header protection feature when the connection is using the ChaCha20-Poly1305 cipher suite. The most likely outcome is connection failure, but if the connection persists despite the high packet loss it could be possible for a network observer to identify packets as coming from the same source despite a network path change.

10) Out-of-bounds read (CVE-ID: CVE-2024-7519)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to a boundary error when processing graphics shared memory. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger an out-of-bounds read and bypass browser sandbox.

11) Type Confusion (CVE-ID: CVE-2024-7520)

CWE-ID: CWE-843 - Type confusion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a type confusion error in WebAssembly. A remote attacker can trick the victim to visit a specially crafted website, trigger a type confusion error and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

12) Out-of-bounds read (CVE-ID: CVE-2024-7522)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to a boundary error in editor component. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger an out-of-bounds read and bypass browser sandbox.

13) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2024-7525)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
