Descriptions

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.

vodozemac es una implementación de Olm y Megolm en Rust puro. Las versiones 0.5.0 y 0.5.1 de vodozemac han degradado las capacidades de puesta a cero secreta, debido a cambios en las dependencias criptográficas de terceros (las cajas Dalek), que movieron las capacidades de puesta a cero secreta detrás de un indicador de característica y desactivaron esta característica de forma predeterminada. Las capacidades degradadas de puesta a cero podrían dar como resultado la producción de más copias de memoria de secretos de cifrado y los secretos podrían permanecer en la memoria más tiempo del necesario. Esto aumenta marginalmente el riesgo de exposición de datos confidenciales. Este problema se solucionó en la versión 0.6.0 y se recomienda a los usuarios que actualicen. No se conocen workarounds para esta vulnerabilidad.
