How to Fix CVE-2024-11862

To remediate this vulnerability, upgrade all affected Devolutions.XTS.NET dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Devolutions.XTS.NET fixed: 2024.11.26 
Upgrade Devolutions.XTS.NET to 2024.11.26
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for Devolutions.XTS.NET

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-11862, inspect your project dependencies for Devolutions.XTS.NET:

inspect dependencies for Devolutions.XTS.NET

Analyze the terminal output to locate any version of Devolutions.XTS.NET in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2024.11.26), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-385: Covert Timing Channel, where covert timing channels convey information by modulating some aspect of system behavior over time, so that the program receiving the information can observe system behavior and infer protected information. In Devolutions.XTS.NET, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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 ### References https://en.wikipedia.org/wiki/Timing_attack
