Description Josh Bressers 2004-09-21 15:09:53 EDT
There's a race in the kernel, and considering the permissions on
/proc/PID/{cmdline,environ} a security bug as well: If you win the
race with a starting process, you can read its environment.

Comment 2 Mark J. Cox (Product Security) 2005-01-10 10:01:07 EST
I believe RHEL2.1 isn't affected by this flaw and RHEL3 is only
affected because of a backported patch.  Moving to NEEDINFO for a
kernel engineer to verify.
Comment 3 Don Howard 2005-09-15 19:25:35 EDT
It looks like this was corrected for RHEL3, but RHEL21 is still vulnerable.
