SixLabors.ImageSharp vulnerable to Memory Allocation with Excessive Size Value
Impact
A vulnerability discovered in the ImageSharp library, where the processing of specially crafted files can lead to excessive memory usage in image decoders. The vulnerability is triggered when ImageSharp attempts to process image files that are designed to exploit this flaw.
This flaw can be exploited to cause a denial of service (DoS) by depleting process memory, thereby affecting applications and services that rely on ImageSharp for image processing tasks. Users and administrators are advised to update to the latest version of ImageSharp that addresses this vulnerability to mitigate the risk of exploitation.
Patches
The problem has been patched. All users are advised to upgrade to v3.1.4 or v2.1.8.
Workarounds
Before calling Image.Decode(Async)
, use Image.Identify
to determine the image dimensions in order to enforce a limit.
