Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Out-of-bounds write (CVE-ID: CVE-2021-45930)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing untrusted input within QtPrivate::QCommonArrayOps::growAppend() function. A remote attacker can create a specially crafted SVG file, trick the victim into opening it using the affected software, trigger an out-of-bounds write and crash the application.
2) Division by zero (CVE-ID: CVE-2023-32573)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a divide by zero error in src/svg/qsvghandler.cpp. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
3) Buffer overflow (CVE-ID: CVE-2023-32763)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing SVG files within the QTextLayout() function in src/gui/text/qtextlayout.cpp. A remote attacker can pass a specially crafted SVG file to the application, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Improper Certificate Validation (CVE-ID: CVE-2023-34410)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to improper validation of TLS certificate chain, where application does not always consider whether the root of a chain is a configured CA certificate. A remote attacker can perform MitM attack.
5) Buffer overflow (CVE-ID: CVE-2023-37369)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing XML content in QXmlStreamReader. A remote attacker can pass specially crafted XML input to the application, trigger memory corruption and perform a denial of service (DoS) attack.
6) Infinite loop (CVE-ID: CVE-2023-38197)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop when handling recursive expansions. A remote attacker can consume all available system resources and cause denial of service conditions.
7) Reachable assertion (CVE-ID: CVE-2025-5455)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion within the qDecodeDataUrl() function in QtCore. A remote attacker can pass a specially crafted data, such as URL with a "charset" parameter but without a value, and crash the application.
