CVE-2023-24607 [HIGH] Qt vulnerabilities
Title: Qt vulnerabilities
Summary: Several security issues were fixed in Qt.
It was discovered that Qt did not correctly handle certain inputs when
using the SQL ODBC driver plugin. An attacker could possibly use this issue
to cause a denial of service. (CVE-2023-24607)
It was discovered that Qt did not correctly parse certain strict-transport-
security headers. An attacker could possibly use this issue to leak
sensitive information. This issue only affected Ubuntu 20.04 LTS and Ubuntu
22.04 LTS. (CVE-2023-32762)
It was discovered that Qt did not correctly handle certain inputs from DNS
servers. A remote attacker could possibly use this issue to execute
arbitrary code or cause a denial of service. (CVE-2023-33285)

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information.
