CVE-2024-41132
Excessive Memory Usage vulnerability in SixLabors.ImageSharp (NuGet)
What is CVE-2024-41132 About?
This vulnerability in the ImageSharp library allows for excessive memory usage when processing specially crafted GIF files. Attackers can exploit this to cause a denial of service by supplying a malicious image. Exploitation is relatively easy, requiring only the provision of a malformed image file.
Affected Software
- SixLabors.ImageSharp
- <2.1.9
- >3.0.0, <3.1.5
Technical Details
The ImageSharp library's Gif decoder is vulnerable to excessive memory usage. When processing an image file specifically crafted to exploit this flaw, the decoder consumes an inordinate amount of memory. This can occur, for instance, by manipulating GIF image metadata or structure to trigger oversized internal buffers or recursive data parsing without proper bounds checking. The vulnerability is triggered during the image processing stage, leading to resource exhaustion and a denial of service condition for applications utilizing the library.
What is the Impact of CVE-2024-41132?
Successful exploitation may allow attackers to cause a denial of service, leading to system instability or unresponsiveness.
What is the Exploitability of CVE-2024-41132?
Exploitation involves supplying a specially crafted image file, which is a low-complexity action. No authentication is required, and the attacker does not need elevated privileges. This is typically a remote attack, as it involves an application processing external, untrusted input. The primary constraint is the application's use of the vulnerable ImageSharp library for image processing. Risk factors include applications that accept and process user-uploaded images, or images from untrusted sources, without proper validation or resource limits.
