Summaryinfo

A vulnerability was found in Matrix libolm up to 3.2.16 and classified as problematic. This affects an unknown function of the component AES. The manipulation results in timing discrepancy. This vulnerability only affects products that are no longer supported by the maintainer. This vulnerability is known as CVE-2024-45191. No exploit is available.

Detailsinfo

A vulnerability classified as problematic has been found in Matrix libolm up to 3.2.16. Affected is an unknown code of the component AES. The manipulation with an unknown input leads to a timing discrepancy vulnerability. CWE is classifying the issue as CWE-208. Two separate operations in a product require different amounts of time to complete, in a way that is observable to an actor and reveals security-relevant information about the state of the product, such as whether a particular operation was successful or not. This is going to have an impact on confidentiality. CVE summarizes:

An issue was discovered in Matrix libolm (aka Olm) 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. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

The advisory is shared for download at soatok.blog. This vulnerability is traded as CVE-2024-45191 since 08/22/2024. The exploitability is told to be difficult. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1592.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
