GHSA-J6VM-4R7G-X4GR

Vulnerability from github – Published: 2024-11-27 19:01 – Updated: 2024-11-27 19:01

Summary

Devolutions.XTS.NET Vulnerable to Timing Attack on GF Multiplications

Details

Impact

Timing attacks on Galois Field multiplications in this package. Successful exploitation would effectively allow a downgrade of the security guarantees of the XTS mode to the security guarantees of ECB mode, allowing block swapping, enabling identification of identical blocks, and rendering half of the XTS key obsolete. Timing attacks require specific conditions to be exploitable.

Patches

Patched in 2024.11.26

Workarounds

Upgrade the package

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
