QSslSocket incorrectly calls SSL_shutdown() in OpenSSL mid-handshake causing denial of service in TLS applications (CVE-2020-13962) This update provides additionals fixes: - Check that the sizes are even representable when checking if clipping is necessary (P300) - Multiply instead of shifting, The shift operator is undefined for negative values. (P301) - Check returns of hex2int in get_hex_rgb, Avoids undefined behavior when trying to shift negative values. (P302) - Sanitize lengthValue in CSS parser, Limit the LengthData to the integer range before rounding it, taking into account that qRound() substracts 1 from negative values. (P303) - QBezier: Don't try calculating a unit vector when length is null. It's undefined and causes a division by zero. (P304) - Avoid potential ub in corrupt bmp file. biHeight may be int_min, in which case qAbs<int>() will not work. (P305) - wasm: disable XDG_RUNTIME_DIR warning XDG is not very relevant on the Web platform. (P306) - Use SOURCE_DATE_EPOCH. Use the standard variable name in addition to the QT-specific one to make builds reproducible out-of-the-box (P308) - Fix notification of QDockWidget when it gets undocked (P309) - Synthesize Enter/LeaveEvent for accepted QTabletEvent (P310) - Fix crash when running QtCore: Stack is misaligned on x86-64 (P311) - Add support for PostgreSQL 12 (P312) - QStandardPaths: Correct handling for XDG_RUNTIME_DIR (P313) - QStandardPaths/Unix: improve the XDG_RUNTIME_DIR creation/detection (P312) - Add remote print queue support (P313)
