Hello. My name is Bruno and I would like to get guidance for a correction in Qt.
An Australian government article pointed to a vulnerability in the writing functionality of Adobe Acrobat Pro DC 2017 ( https://www.cyber.gov.au/acsc/view-all-content/publications/examination-redaction-functionality-adobe-acrobat -pro-dc-2017). The vulnerability refers to the values of CMap objects ordered in order to reproduce parts of text. The vulnerability is present in Qt. I think it would be a good idea to make a correction in Qt. I wrote a correction for the wkhtmltopdf project ( https://github.com/wkhtmltopdf/qt/pull/47). But it is version 4.8.7. I ask them, what would be the best way for the correction to be formally carried out under Qt? I send the question to someone, specifically? Or should I set up a development environment, within Qt standards, and send a commit? If I have to do this, is there any step by step on how to contribute? Does the contribution occur in the github environment? Or is another repository used? I thank the attention, hugs, Bruno
