https://notcve.org/view.php?id=CVE-2020-11810
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. • https://bugzilla.suse.com/show_bug.cgi?id=1169925 https://community.openvpn.net/openvpn/ticket/1272 https://github.com/OpenVPN/openvpn/commit/37bc691e7d26ea4eb61a8a434ebd7a9ae76225ab https://lists.debian.org/debian-lts-announce/2022/05/msg00002.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FGHHV4YZANZW45KZTJJGVGPFMSXYRCKZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JII7RYYYRBPQNEGGVSOXCM7JUZ43T3VH https://patchwork.openvpn.net/patch/ • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

openvpnserv.exe (aka the interactive service helper) in OpenVPN 2.4.x before 2.4.6 allows a local attacker to cause a double-free of memory by sending a malformed request to the interactive service. This could cause a denial-of-service through memory corruption or possibly have unspecified other impact including privilege escalation. openvpnserv.exe (también conocido como interactive service helper) en OpenVPN en versiones 2.4.x anteriores a la 2.4.6 permite que un atacante local provoque una doble liberación (double free) de memoria enviando una petición mal formada al servicio interactivo. Esto podría provocar una denegación de servicio (DoS) al corromper la memoria o, posiblemente, otro impacto no especificado, incluyendo el escalado de privilegios. • http://www.slackware.com/security/viewer.php?l=slackware-security&y=2018&m=slackware-security.568761 https://community.openvpn.net/openvpn/wiki/ChangesInOpenvpn24 https://github.com/OpenVPN/openvpn/commit/1394192b210cb3c6624a7419bcf3ff966742e79b https://github.com/OpenVPN/openvpn/releases/tag/v2.4.6 https://www.tenable.com/security/research/tra-2018-09 • CWE-415: Double Free •
