Summary

Firefox 1.0 does not prevent the user from dragging an executable file to the desktop when it has an image/gif content type but has a dangerous extension such as .bat or .exe, which allows remote attackers to bypass the intended restriction and execute arbitrary commands via malformed GIF files that can still be parsed by the Windows batch file parser, aka "firedragging."

Patch / fix

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
