Description Robert Scheck 2004-01-06 12:31:31 EST
Description of problem, how reproducible and steps to reproduce:
Mod_php under Apache 2.0.x leaks a critical file descriptor that 
can be used to takeover (hijack) the https service.

All in all it's described at Bugtraq:

Version-Release number of selected component (if applicable):

Actual results:
I talked with a guy of php.net, he said, that it is an Apache 
related problem, so something like that is maybe possible with 
phyton, too. He said too, that Apache will provide a patch for 
that - anytime...

Expected results:
Fixed httpd asap ;) the fix is like this:

  fcntl( X, F_SETFD, FD_CLOEXEC );

But the question is where to place it, X should also be replaced
with the real variable's name. 

Additional info:
Red Hat Linux 9 is vulnerable, too.

This "leaking" of file descriptors does not have security implications
unless you consider that the PHP interpreter provides a "security
sandbox" from which it is possible to run untrusted code.  For further
information, read our write-up in ApacheWeek:
