Vulnerable version of libwebp and can be exploited with a malicious source image
Impact
This vulnerability affects deployments of FreeImage that involve decoding or processing malicious source .webp files. If you only process your own trusted files, this should not affect you, but you should remove FreeImage from your project, as it is not maintained and presents a massive security risk.
If you are using FreeImage via ImageResizer.Plugins.FreeImage, please utilize Imageflow or Imageflow.Server instead, or upgrade to ImageResizer 5 and use ImageResizer.Plugins.Imageflow (enable Prereleases on NuGet to access).
FreeImage relies on Google's libwebp library to decode .webp images, and is affected by the recent zero-day out-of-bounds write vulnerability CVE-2023-4863 and https://github.com/advisories/GHSA-j7hp-h8jx-5ppr. The libwebp vulnerability also affects Chrome, Android, macOS, and other consumers of the library).
libwebp patched the vulnerability and released 1.3.2. FreeImage hasn't been updated since then and is presumed vulnerable.
Patches
None. FreeImage has not been updated in several years.
Workarounds
If you are using ImageResizer.Plugins.FreeImage, please utilize Imageflow or Imageflow.Server instead, or upgrade to ImageResizer 5 and use ImageResizer.Plugins.Imageflow (enable Prereleases on NuGet to access).
