NixOS vulnerability analysis and mitigation

A vulnerability has been discovered in Comodo Dragon browser versions up to 134.0.6998.179, identified as CVE-2025-8205. The issue affects the IP DNS Leakage Detector component and involves cleartext transmission of sensitive information. The vulnerability was disclosed in July 2025 and impacts the browser's security features related to DNS handling (NVD).

The vulnerability stems from the browser's built-in 'IP / DNS Leakage Detector' extension, which uses insecure HTTP connections for its operations. The issue has been assigned a CVSS v3.1 base score of 3.7 (LOW) with the vector string CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N. The vulnerability is classified under CWE-319 (Cleartext Transmission of Sensitive Information) and CWE-310 (Cryptographic Issues) (NVD, FMISEC).

The vulnerability allows attackers to potentially intercept sensitive information transmitted in cleartext through the IP DNS Leakage Detector component. Additionally, when combined with DNS spoofing attacks, it can lead to exposure of user data and potential manipulation of the browser's security indicators (FMISEC).

The vendor was contacted regarding this disclosure but did not respond. No official patches or fixes have been released at the time of reporting. Users are advised to consider using alternative browsers with proper security implementations until a fix is available (NVD).
