| Beschreibung: | Summary: The remote host is missing an update for the 'nextcloud-client' package(s) announced via the MGASA-2021-0421 advisory. Vulnerability Insight: Nextcloud Desktop Client before 3.3.1 is vulnerable to improper certificate validation due to lack of SSL certificate verification when using the 'Register with a Provider' flow. (CVE-2021-22895) In versions prior to 3.3.0, the Nextcloud Desktop client fails to check if a private key belongs to previously downloaded public certificate. If the Nextcloud instance serves a malicious public key, the data would be encrypted for this key and thus could be accessible to a malicious actor. This issue is fixed in Nextcloud Desktop Client version 3.3.0 Affected Software/OS: 'nextcloud-client' package(s) on Mageia 8. Solution: Please install the updated package(s). CVSS Score: 4.3 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:P/A:N |
