Description
This security bulletin contains information about 14 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2014-1745)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing vectors that trigger removal of an SVGFontFaceElement object, related to core/svg/SVGFontFaceElement.cpp. A remote attackers can cause a denial of service or possibly have unspecified other impact.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
2) Use-after-free (CVE-ID: CVE-2023-40414)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in WebKit. A remote attacker can trick the victim to visit a specially crafted website, trigger a use-after-free error and execute arbitrary code on the system.
3) Buffer overflow (CVE-ID: CVE-2023-42833)
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 trick the victim to visit 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.
4) Spoofing attack (CVE-ID: CVE-2023-42843)
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 address bar.
5) Use-after-free (CVE-ID: CVE-2023-42950)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing HTML content in WebKit. A remote attacker can trick the victim to visit 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) Buffer overflow (CVE-ID: CVE-2023-42956)
The vulnerability allows a remote attacker to crash the browser
The vulnerability exists due to a boundary error when processing web content in WebKit. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger memory corruption and crash the browser.

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 visit a specially crafted web page, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
8) Buffer overflow (CVE-ID: CVE-2024-23213)
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 visit a specially crafted web page, 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) Type confusion (CVE-ID: CVE-2024-23222)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a type confusion error when processing HTML content. A remote attacker can trick the victim to open 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.
Note, the vulnerability is being actively exploited in the wild.
10) Buffer overflow (CVE-ID: CVE-2024-23252)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing HTML content in WebKit. A remote attacker can trick the victim to visit a specially crafted website and crash the browser.
11) Information disclosure (CVE-ID: CVE-2024-23254)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
