Description

The remote host is affected by the vulnerability described in GLSA-202402-21 (QtNetwork: Multiple Vulnerabilities)

- An issue was discovered in Qt before 5.15.14, 6.x before 6.2.9, and 6.3.x through 6.5.x before 6.5.1. Qt Network incorrectly parses the strict-transport-security (HSTS) header, allowing unencrypted connections to be established, even when explicitly prohibited by the server. This happens if the case used for this header does not exactly match. (CVE-2023-32762)

- An issue was discovered in the HTTP2 implementation in Qt before 5.15.17, 6.x before 6.2.11, 6.3.x through 6.5.x before 6.5.4, and 6.6.x before 6.6.2. network/access/http2/hpacktable.cpp has an incorrect HPack integer overflow check. (CVE-2023-51714)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

All Qt 5 users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose >=dev-qt/qtnetwork-5.15.12-r1 All Qt 6 users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose >=dev-qt/qtbase-6.6.1-r2
