Summary
openvpn vulnerabilities
Details
Reynir Björnsson discovered that OpenVPN incorrectly handled terminating client connections. A remote authenticated client could possibly use this issue to keep the connection active, bypassing certain security policies. This issue only affected Ubuntu 23.10, and Ubuntu 24.04 LTS. (CVE-2024-28882)
Reynir Björnsson discovered that OpenVPN incorrectly handled certain control channel messages with nonprintable characters. A remote attacker could possibly use this issue to cause OpenVPN to consume resources, or fill up log files with garbage, leading to a denial of service. (CVE-2024-5594)
