TIFF Decoder Unbounded Memory Consumption via Large Tiles

Executive Summary

This vulnerability exists in the TIFF image decoder, where it does not impose a limit on the size of tiles in tiled images. As a result, a malicious or corrupted TIFF image containing an extremely large tile can cause the decoder to consume an unbounded amount of memory.

Impact Analysis

The impact of this vulnerability is that processing a specially crafted TIFF image can lead to excessive memory consumption. This can cause the application or system handling the image to slow down, become unstable, or crash due to resource exhaustion.

Detection Guidance

This vulnerability involves the TIFF decoder in the golang.org/x/image package not limiting tile sizes in tiled images, which can cause unbounded memory consumption when processing malicious or corrupt TIFF images.

Detection would involve monitoring for unusually high memory usage or crashes in applications using this TIFF decoder when processing TIFF images.

There are no specific commands provided in the available resources to detect this vulnerability directly on a network or system.

Mitigation Strategies

Immediate mitigation involves avoiding processing untrusted or potentially malicious TIFF images with the vulnerable golang.org/x/image/tiff package versions prior to v0.43.0.

Monitoring and limiting memory usage of applications that decode TIFF images can help reduce the risk of denial-of-service conditions.

Applying updates to the golang.org/x/image package to version v0.43.0 or later, where the vulnerability is fixed, is the recommended long-term mitigation.
