This page provides security- and maintenance-relevant information for the 3rd party code in Qt. For a complete list of 3rd party modules, including the currently included version, see the documentation page with the list of licenses used in Qt.

repository	Qt module	3rdparty module	processed untrusted content	patches	upstream	upgrade process
qtbase	Qt Core	pcre2	regular expressions	-	http://www.pcre.org/	Routine pre-release checks of their release page on GitHub. Their front-page is lagging a little behind at time of writing.
qtbase	Qt Core	sha1	arbitrary stream of bytes	-	https://www.dominik-reichl.de/projects/csha1/	Replace the .cpp file with the new version from upstream
qtbase	Qt Core	sha{224,256,384,512}	arbitrary stream of bytes	-	https://www.rfc-editor.org/rfc/rfc6234#section-8	None, maybe look at errata or CVEs
qtbase	Qt Core	sha3	arbitrary stream of bytes	A patch that addresses CVE-2022-37454	https://keccak.team/archives.html	None, the upstream implementation is obsolete. Look for CVEs
qtbase	Qt Core	tinycbor	Streaming CBOR object	-	https://github.com/intel/tinycbor	Thiago is its maintainer, so brings us updates when he makes them.
qtbase	Qt Core	zlib	zlib compressed data	build fixes for Windows and Apple; exporting symbols	http://zlib.net/	Routine pre-release check of their front page, which links the latest release.
qtbase	Qt GUI	harfbuzz-ng	fonts	-
qtbase	Qt GUI	freetype	fonts	-	https://gitlab.freedesktop.org/freetype	fetch latest tar-ball, run script. Might involve manual fixing of license and build system files, depending on what changed upstream.
qtbase	Qt GUI	libpng	PNG images	-	http://www.libpng.org/pub/png/libpng.html
qtbase	Qt GUI	libjpeg	JPEG images	-	https://sourceforge.net/projects/libjpeg-turbo/
qtbase	Qt GUI	md4c	markdown text	Fix compiler warnings with MSVC
qtbase	Qt GUI	emoji segmenter	any visual text		https://github.com/google/emoji-segmenter/	Fetch latest version tag from repository and copy in the files
qtbase	Qt Network	Public Suffix List	only indirectly	-	https://publicsuffix.org/list/ https://github.com/publicsuffix/list	Download the recent version of the list (https://publicsuffix.org/list/public_suffix_list.dat) Then, for >=6.5 - follow the instructions in src/3rdparty/libpsl/README.txt For 6.2 (while it's supported) (easiest on Linux/Unix): - Build the tool in ./util/publicSuffix - Run once to see instructions - Follow the instructions - You have to manually replace the appropriate section of qurltlds_p.h For 5.15 (while it's supported) (easiest on Linux/Unix) - Same as for 6.2, except the tool is located in util/corelib/qurl-generateTLDs, and the qurltlds file is in another location - note: the instructions in 5.15 require stripping comments from the .dat file, which is different to the 6.2 branch Finally, for all versions: Bump qt_attribution.json SHA to the SHA the .dat file was generated from in their repo. Basically just go through commits from the top until you see the changes from that commit in the .dat file.
qtbase	Qt SQL	sqlite	SQL database files and queries	-	https://sqlite.org	Download the latest source code amalgation package and unzip into relevant directory
