The QSslSocket::sslErrors function in Qt before 4.6.5, 4.7.x before 4.7.6, 4.8.x before 4.8.5, when using certain versions of openSSL, uses an "incompatible structure layout" that can read memory from the wrong location, which causes Qt to report an incorrect error when certificate validation fails and might cause users to make unsafe security decisions to accept a certificate.

Security readout for executives and security teams

This flaw affects older Qt applications using QSslSocket with certain OpenSSL versions. When certificate validation fails, Qt may report the wrong error, which can mislead users into accepting an unsafe certificate. The main business risk is weakened trust decisions in software that relies on TLS certificate warnings. Exposure is most likely in legacy desktop or server applications built with affected Qt 4 branches and OpenSSL combinations. Modern systems are less likely affected unless they bundle old Qt libraries or depend on unmaintained distribution packages. Treat this as a legacy dependency hygiene issue with security impact. Prioritize remediation where affected Qt applications protect sensitive communications, process credentials, or allow users to bypass certificate warnings. Mitigation focus: Upgrade Qt to 4.6.5, 4.7.6, 4.8.5, or vendor-fixed packages.; Apply distribution advisories from Ubuntu, openSUSE, Debian, or other affected vendors.; Identify applications bundling their own Qt runtime, not only system packages..
