CVE-2005-2261: n/a vulnerability

CVE-2005-2261: Firefox before 1.0.5, Thunderbird before 1.0.5, Mozilla before 1.7.9, Netscape 8.0.2, and K-Meleon 0.9 runs...

Firefox before 1.0.5, Thunderbird before 1.0.5, Mozilla before 1.7.9, Netscape 8.0.2, and K-Meleon 0.9 runs XBL scripts even when Javascript has been disabled, which makes it easier for remote attackers to bypass such protection.

Security readout for executives and security teams

This flaw affects very old Mozilla-family browsers and Thunderbird. Disabling JavaScript did not fully stop XBL scripts, so a remote site or content could bypass a user’s intended script-blocking protection. The source bundle does not show data theft, code execution, or current exploitation evidence. Exposure is most plausible in legacy endpoints, archived builds, kiosks, lab systems, or mail workflows still using the listed 2005-era clients. Modern supported browsers are not identified as affected in the supplied sources. Treat as a legacy hygiene issue unless old Mozilla-family clients remain in use. If present, prioritize removal or upgrade because the affected software defeats a user-selected script protection. Mitigation focus: Upgrade affected products to vendor-fixed versions or later supported replacements.; Check vendor advisories for distribution-specific packages and backports.; Remove obsolete browser and mail clients from managed endpoints..
