This security bulletin contains information about 3 vulnerabilities.
1) Infinite loop
EUVDB-ID: #VU78697
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-38197
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe 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.
MitigationInstall updates from vendor's website.
Vulnerable software versionsQt: 5.0 - 6.5.2

CVE-ID: CVE-2023-34410
CWE-ID:
CWE-295 - Improper Certificate Validation
Exploit availability: No
DescriptionThe 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.
