Description William Au 2003-03-13 16:34:33 EST

Description of problem: 

Fopen hardcodes 0666 as mode.  So during an rpm install, the files created
will have a mode of 666 and thus can be overwritten by anyone on the system
until chmod() is called.

Comment 1 Jeff Johnson 2003-03-14 15:44:04 EST

No, files are created 0666 iff umask is 000, and that's
a configuration choice and/or problem.

Fopen calls open(2), and the mode passed to the system call
is adjusted by the current umask, typically 022, resulting
in mode 0644 for newly created files.
