"value": "ag-psd is a JavaScript library for reading and writing Photoshop Document files. Prior to 31.0.3, readPsd() accepts a totalMemoryLimit for parsing untrusted PSD files, but decodeLayerImageData expects a differently named memoryLimit property and therefore passes an undefined limit to createImageDataBitDepth. An attacker who can supply a PSD to an application with layer decoding enabled can use attacker-controlled layer dimensions to trigger an allocation larger than the configured limit, causing process memory exhaustion and denial of service. The advisory also identifies inflateSync(compressed) decompressing ZIP-encoded channel data without an output-size cap, which can cause a similar denial of service through unbounded decompression. This vulnerability is fixed in 31.0.1."
