Name of the Vulnerable Software and Affected Versions

Qt versions 6.x prior to 6.2.11
Qt versions 6.3.x through 6.5.x prior to 6.5.4
Qt versions 6.6.x prior to 6.6.2
Description
An issue was discovered in the HTTP2 implementation in Qt, related to an incorrect HPack integer overflow check in the
network/access/http2/hpacktable.cpp file. This issue can cause an integer overflow when receiving more than 4 GB of total HTTP header data or 2 GB for a single header, potentially allowing an attacker to write data beyond the allocated buffer, leading to a denial of service.Recommendations
For Qt versions prior to 5.15.17, update to version 5.15.17 or later.
For Qt versions 6.x prior to 6.2.11, update to version 6.2.11 or later.
For Qt versions 6.3.x through 6.5.x prior to 6.5.4, update to version 6.5.4 or later.
For Qt versions 6.6.x prior to 6.6.2, update to version 6.6.2 or later.
