Security advisory: zlib in Qt

zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow in inflate in inflate.c via a large gzip header extra field and has been assigned the CVE id CVE-2022-37434.

As this only affects applications that call inflateGetHeader directly then applications using Qt are not directly affected by this at all. The symbol may still be exploited if used in conjunction with another vulnerability or if the application uses this function directly.

Solution: Apply the following patches (two from Gerrit, or single downloadable patch) or update to Qt 6.4.0, Qt 6.3.2, Qt 6.2.6 or Qt 5.15.11
