SixLabors.ImageSharp vulnerable to Memory Allocation with Excessive Size Value

CVE-2024-32035 / GHSA-g85r-6x2q-45w7

More information

Details

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.

Advisories and Breaking Changes

Major breaking changes

• Due to the new unmanaged memory engine, we had to redesign our pixel processing and low level memory management API-s. The most visible change is that the GetPixelRowSpan() methods have been replaced with ProcessPixelRows() variants. This was done to guarantee memory safety. For more details see:
  • 2.0 documentation on Working with Pixel Buffers
  • 2.0 documentation on Memory Management
  • Pixel processing breaking changes & API discussion - #​1739
• Png and Jpeg now decode to pixels formats closer to the encoded format when using the non-generic API. (For example Jpeg now decodes to Image<Rgb24> instead of Image<Rgba32>.) This was done to reduce memory usage and remove some surprises for users.
• We've dropped the old NetStandard 1.3 target. This targeted frameworks not supported by Microsoft and was adding overhead to development.

Complete list of breaking PR-s

• Add Abgr32 pixel type, extend IPixel - #​1886 via @​ynse01, @​antonfirsov, @​JimBobSquarePants
• Remove netstandard 1.3 target - #​1888 via @​JimBobSquarePants
• ImageFormatDetector Configuration Cleanup - #​1936 via @​JimBobSquarePants
