CVE-2024-34063

This marginally increases the risk of sensitive data exposure.

LOW 2.5EPSS 0.14%

Does this matter?

Lower severity and a low EPSS score (0.14%). Track it; it rarely justifies an emergency change on its own.

Description

vodozemac is an implementation of Olm and Megolm in pure Rust. Versions 0.5.0 and 0.5.1 of vodozemac have degraded secret zeroization capabilities, due to changes in third-party cryptographic dependencies (the Dalek crates), which moved secret zeroization capabilities behind a feature flag and defaulted this feature to off. The degraded zeroization capabilities could result in the production of more memory copies of encryption secrets and secrets could linger in memory longer than necessary. This marginally increases the risk of sensitive data exposure. This issue has been addressed in version 0.6.0 and users are advised to upgrade. There are no known workarounds for this vulnerability.
