Machine-written summary

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

SixLabors.ImageSharp versions before 2.1.8 and from 3.0.0 before 3.1.4 are vulnerable. An attacker who can supply a specially crafted image file for processing can cause excessive memory usage in the image decoders, leading to denial of service by exhausting process memory. Upgrade to version 2.1.8 or 3.1.4. Before calling Image.Decode or Image.DecodeAsync, call Image.Identify to check image dimensions and enforce a size limit.
