Descriptions

An issue was discovered in Qt before 5.15.14, 6.x before 6.2.9, and 6.3.x through 6.5.x before 6.5.1. Qt Network incorrectly parses the strict-transport-security (HSTS) header, allowing unencrypted connections to be established, even when explicitly prohibited by the server. This happens if the case used for this header does not exactly match.

This update for libqt5-qtbase fixes the following issues. Fixed Qt SQL ODBC driver plugin DOS. Fixed Qt Network incorrectly parses the strict-transport-security header. Fixed buffer overflow when rendering an SVG file with an image inside it. Fixed buffer overflow in QDnsLookup. Fixed certificate validation does not always consider whether the root of a chain is a configured CA certificate. Fixed infinite loops in QXmlStreamReader.
