Descripción:	Summary: The remote host is missing an update for the 'openvpn' package(s) announced via the MGASA-2020-0195 advisory. Vulnerability Insight: Updated openvpn packages fix security vulnerability: An issue was discovered in OpenVPN 2.4.x before 2.4.9. An attacker can inject a data channel v2 (P_DATA_V2) packet using a victim's peer-id. Normally such packets are dropped, but if this packet arrives before the data channel crypto parameters have been initialized, the victim's connection will be dropped. This requires careful timing due to the small time window (usually within a few seconds) between the victim client connection starting and the server PUSH_REPLY response back to the client. This attack will only work if Negotiable Cipher Parameters (NCP) is in use (CVE-2020-11810). The openvpn package has been updated to version 2.4.9, fixing the issue and other bugs. See the upstream release notes for details. Affected Software/OS: 'openvpn' package(s) on Mageia 7. Solution: Please install the updated package(s). CVSS Score: 4.3 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:N/A:P
