Summary

olm-sys: wrapped library unmaintained, potentially vulnerable

Details

After several cryptographic vulnerabilities in libolm were disclosed publicly, the Matrix Foundation has officially deprecated the library. olm-sys is a thin wrapper around libolm and is now deprecated and potentially vulnerable in kind.

Users of olm-sys and its higher-level abstraction, olm-rs, are highly encouraged to switch to vodozemac as soon as possible. It is the successor effort to libolm and is written in Rust.

CVE-2024-45191 (GCVE-0-2024-45191)

Vulnerability from cvelistv5 – Published: 2024-08-22 00:00 – Updated: 2024-09-10 18:21 Unsupported When Assigned

Summary

An issue was discovered in Matrix libolm through 3.2.16. The AES implementation is vulnerable to cache-timing attacks due to use of S-boxes. This is related to software that uses a lookup table for the SubWord step. This refers to the libolm implementation of Olm. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

CVE-2024-45193 (GCVE-0-2024-45193)

Vulnerability from cvelistv5 – Published: 2024-08-22 00:00 – Updated: 2024-09-10 18:34 Unsupported When Assigned

Summary

An issue was discovered in Matrix libolm through 3.2.16. There is Ed25519 signature malleability due to lack of validation criteria (does not ensure that S < n). This refers to the libolm implementation of Olm. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

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.
