Package	Ecosystem	Affected	Fixed in
SixLabors.ImageSharp	NuGet	<2.1.9 \|\| >=3.0.0, <3.1.5	2.1.9, 3.1.5

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

SixLabors.ImageSharp versions before 2.1.9 and from 3.0.0 before 3.1.5 are vulnerable. An attacker who can supply a specially crafted GIF file for ImageSharp to process can cause excessive memory usage in the GIF decoder. Upgrade to 2.1.9 or 3.1.5. As a workaround, call Image.Identify to check image dimensions before calling Image.Decode or Image.DecodeAsync, and enforce a limit on them.
