Description

This security bulletin contains information about 5 vulnerabilities.


1) Division by zero (CVE-ID: CVE-2023-32573)

CWE-ID: CWE-369 - Divide By Zero

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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.


2) Out-of-bounds read (CVE-ID: CVE-2023-33285)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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.


3) Improper Certificate Validation (CVE-ID: CVE-2023-34410)

CWE-ID: CWE-295 - Improper Certificate Validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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.


4) Buffer overflow (CVE-ID: CVE-2023-37369)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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.


5) Infinite loop (CVE-ID: CVE-2023-38197)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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.
