Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2024-40776)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing HTML content. A remote attacker can trick the victim to open 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.
2) Out-of-bounds read (CVE-ID: CVE-2024-40789)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger an out-of-bounds read error and crash the browser.
3) Out-of-bounds read (CVE-ID: CVE-2024-40780)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger an out-of-bounds read error and read contents of memory on the system.
4) Out-of-bounds read (CVE-ID: CVE-2024-40779)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger an out-of-bounds read error and read contents of memory on the system.
5) Use-after-free (CVE-ID: CVE-2024-40782)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing HTML content. A remote attacker can trick the victim to open 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.
6) Spoofing attack (CVE-ID: CVE-2024-40866)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of user-supplied data in WebKit. A remote attacker can spoof the browser's address bar.
7) Security features bypass (CVE-ID: CVE-2024-23271)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to a logic error in WebKit, which can lead to unexpected cross-origin behavior. A remote attacker can trick the victim to visit a specially crafted website and bypass implemented security restrictions.
8) Buffer overflow (CVE-ID: CVE-2024-27820)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in WebKit Web Inspector. 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.
9) Information disclosure (CVE-ID: CVE-2024-27838)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output in WebKit. A remote attacker can fingerprint website users.
10) Buffer overflow (CVE-ID: CVE-2024-27851)
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 in WebKit. 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.
11) Protection Mechanism Failure (CVE-ID: CVE-2024-44187)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to an error when handling "iframe" elements in WebKit. A remote attacker can exfiltrate data cross-origin.
