Mageia 2021-0200: qtbase5 security update
Summary
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
- 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)
