Description
This security bulletin contains information about 14 secuirty vulnerabilities.
1) Processor optimization removal or modification of security-critical code (CVE-ID: CVE-2024-3852)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to GetBoundName can return the wrong version of an object when JIT optimizations were applied. A remote attacker can abuse such behavior to execute arbitrary code on the system.
2) Buffer overflow (CVE-ID: CVE-2024-3864)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing HTML content. A remote attacker can trick the victim to open a specially crafted website, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Buffer overflow (CVE-ID: CVE-2024-3865)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing HTML content. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Resource exhaustion (CVE-ID: CVE-2024-3302)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when handling HTTP/2 CONTINUATION frames. A remote attacker can trick the victim to visit a specially crated website and perform a denial of service (DoS) attack.
5) Use-after-free (CVE-ID: CVE-2024-3853)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error. A remote attacker can trick the victim to visit a specially crafted website and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
6) Processor optimization removal or modification of security-critical code (CVE-ID: CVE-2024-3854)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to incorrect optimization, when some code patterns in the JIT incorrectly optimized switch statements and generated code with out-of-bounds-reads. A remote attacker can abuse such behavior to execute arbitrary code on the system.
7) Processor optimization removal or modification of security-critical code (CVE-ID: CVE-2024-3855)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to JIT incorrectly optimized MSubstr operations. A remote attacker can trick the victim to visit a specially crafted website, trigger an out-of-bounds read and potentially compromise the affected system.
8) Use-after-free (CVE-ID: CVE-2024-3856)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error during WASM garbage collection. A remote attacker can trick the victim to visit a specially crafted website and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
9) Processor optimization removal or modification of security-critical code (CVE-ID: CVE-2024-3857)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to incorrect optimization when JIT created incorrect code for arguments in certain cases. A remote attacker can abuse such behavior to execute arbitrary code on the system.
10) Buffer overflow (CVE-ID: CVE-2024-3858)
The vulnerability allows a remote attacker to crash the browser.
The vulnerability exists due to a boundary error when processing JavaScript. A remote attacker can mutate a JavaScript object so that the JIT could crash while tracing it.
11) Integer overflow (CVE-ID: CVE-2024-3859)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to integer overflow when handling OpenType fonts. A remote attacker can trick the victim to visit a specially crafted website and gain access to sensitive information.
12) Resource exhaustion (CVE-ID: CVE-2024-3860)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when tracing empty shape lists. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
13) Use-after-free (CVE-ID: CVE-2024-3861)
The vulnerability allows a remote attacker to crash the browser.
The vulnerability exists due to a use-after-free error. If an AlignedBuffer were assigned to itself, the subsequent self-move could result in an incorrect reference count and later use-after-free.
14) Access of uninitialized pointer (CVE-ID: CVE-2024-3862)
The vulnerability allows a remote attacker to crash the browser.
The vulnerability exists due to usage of uninitialized memory in MarkStack assignment operator. A remote attacker can trick the victim to visit the website and crash the browser.
