CVE-2023-41064: Buffer Overflow Issue Addressed with Improved Memory Handling in Various Apple Software

Apple recently addressed a buffer overflow issue (CVE-2023-41064) in various software versions, including macOS Monterey 12.6.9, macOS Big Sur 11.7.10, macOS Ventura 13.5.2, iOS 16.6.1 and iPadOS 16.6.1, iOS 15.7.9 and iPadOS 15.7.9. The vulnerability arises from processing a maliciously crafted image, which may lead to arbitrary code execution. Apple has acknowledged a report suggesting that this issue may have been actively exploited in the wild.

Bug Details

Buffer overflow vulnerabilities occur when a program writes more data to a fixed-length buffer than it can hold, causing adjacent memory locations to be overwritten. This can trigger crashes, data corruption, or even allow an attacker to execute arbitrary code on the affected system.

The CVE-2023-41064 vulnerability specifically affects the way Apple's software handles memory when processing a rogue image file. As a result, an attacker can craft a malicious image and trick the user into opening it, which then allows the attacker to execute arbitrary code on the user's system.

Exploit Details

While precise exploit details have not been publicly disclosed, the vulnerability's existence in multiple Apple software versions indicates that it is a powerful tool for potential attackers. Considering Apple's acknowledgment of the active exploit, users are urged to apply the relevant updates as soon as possible to mitigate the risk of being compromised.

The Patch

Apple's security update includes improved memory handling techniques that address the buffer overflow issue. The patch prevents the overwriting of adjacent memory locations and ensures that no arbitrary code execution is possible when processing an image file.

iOS 15.7.9 and iPadOS 15.7.9
