String handling functions in Mozilla 1.7.3, Firefox 1.0, and Thunderbird before 1.0.2, such as the nsTSubstring_CharT::Replace function, do not properly check the return values of other functions that resize the string, which allows remote attackers to cause a denial of service and possibly execute arbitrary code by forcing an out-of-memory state that causes a reallocation to fail and return a pointer to a fixed address, which leads to heap corruption.Show less

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."Show less
