Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Cleartext transmission of sensitive information (CVE-ID: CVE-2023-32762)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to Qt Network incorrectly parses the strict-transport-security (HSTS) header, allowing unencrypted connections to be established, even when explicitly prohibited by the server. A remote attacker with ability to intercept network traffic can gain access to sensitive data.
2) 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.
3) Out-of-bounds read (CVE-ID: CVE-2023-33285)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to buffer over-read via a crafted reply from a DNS server within the QDnsLookup() function in src/network/kernel/qdnslookup_unix.cpp. A remote attacker can perform a denial of service attack.
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) 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.
