CVE-2024-54534 is an important security vulnerability that has been identified and addressed in several Apple products, including watchOS, visionOS, tvOS, macOS, Safari, iOS, and iPadOS. This vulnerability is related to improper memory handling, which could lead to memory corruption when processing maliciously crafted web content. Memory corruption issues are critical, as they can potentially compromise the security of the affected system or application and lead to unwanted consequences. This article will discuss the details of this vulnerability, the patch updates, and how it can be exploited.

The following code snippet demonstrates an example of how the memory corruption issue could occur

function vulnerableFunction() {
    let maliciousArray = [1, 2, 3, 4, 5];
    let index = 10;

    // This line of code incorrectly accesses out-of-bound memory
    let memoryValue = maliciousArray[index];
}

In this example, the vulnerableFunction() attempts to access an out-of-bound index (10) on the maliciousArray. This can cause memory corruption, depending on how the compiler has allocated memory for the array. It's important to note that the specific technique used to exploit this vulnerability may vary depending on the implementation and target platform.

Exploit Details

Hackers can exploit this vulnerability by crafting malicious web content designed to trigger memory corruption. This can result in potential disclosure of sensitive information, crash of the browser or application, or even arbitrary code execution.

For example, an attacker could create a malicious website with embedded JavaScript code designed to take advantage of this vulnerability. When a user visits the website, the attacker's code can manipulate memory in a way that causes the targeted system or application to become unstable, disclose information, or run arbitrary code under the context of the user.

iPadOS 18.2

Users are advised to update their devices to the latest software versions available to ensure protection against this vulnerability.

Conclusion

CVE-2024-54534 is a memory corruption issue caused by processing malicious web content. This vulnerability can lead to unwanted consequences, including sensitive information disclosure, application crashes, and arbitrary code execution. Users should update their devices to the latest software versions as detailed in this article to protect themselves against this vulnerability.
