CVE-2011-4108: The DTLS implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f performs a MAC check only if certain...

Security readout for executives and security teams

This flaw affected OpenSSL’s DTLS handling and could let a remote attacker infer protected message contents through a padding oracle weakness. It is old, but important where legacy DTLS services or embedded products still use vulnerable OpenSSL versions. Exposure is most likely in legacy systems, appliances, or applications using DTLS with OpenSSL before 0.9.8s or 1.0.0f. The bundle also cites multiple downstream vendor advisories, indicating packaged product impact varied by platform. Treat this as a legacy encryption exposure. Prioritize internet-facing DTLS services, security appliances, VPN-like services, and unsupported systems where old OpenSSL may remain embedded. Mitigation focus: Inventory DTLS-enabled services and products using OpenSSL.; Upgrade OpenSSL to 0.9.8s, 1.0.0f, or later supported releases.; Apply applicable operating system and vendor security advisories..
