Out of Bounds Write Flaw in DGifSlurp of dgif_lib.c Affects Android Devices
CVE-2024-49749
What is CVE-2024-49749?
CVE-2024-49749 refers to a critical vulnerability found in the DGifSlurp function within the dgif_lib.c file, which is part of the Android operating system. This vulnerability arises from an out-of-bounds write due to an integer overflow, enabling remote code execution without requiring any user interaction. Such a flaw poses a notable risk to organizations that rely on Android devices, as it leaves them vulnerable to malicious actors who could potentially gain unauthorized access and control over their systems.
Technical Details
The root cause of CVE-2024-49749 lies within the handling of GIF files in the Android platform. Specifically, an integer overflow occurs during certain processing tasks, which can lead to memory corruption and the possibility of executing arbitrary code remotely. Given that no user interaction is required for an exploit to be executed, this vulnerability could be leveraged by attackers to compromise devices that handle GIF files, elevating concerns for widespread exploitation across various Android-based platforms.
Potential Impact of CVE-2024-49749
-
Remote Code Execution: The most severe impact of CVE-2024-49749 is the potential for remote code execution. Attackers can exploit this vulnerability to run malicious code on affected devices, potentially gaining full control over the system without any user intervention.
-
Compromise of Confidential Data: With the ability to execute arbitrary code, malicious actors could access sensitive information stored on infected devices. This could lead to data breaches involving personal or corporate information, significantly undermining an organization’s data security posture.
-
Increased Attack Surface: Given the pervasive use of Android devices in both personal and enterprise environments, the exploitation of this vulnerability could lead to a broader attack surface. As more devices become compromised, the risk extends to networks and infrastructures that rely on these devices, creating a ripple effect that could impact numerous services and operations.
