Description Josh Bressers 2004-09-21 15:12:11 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.

Might be 2.6 only
fixed in 2.6.9

Comment 2 Mark J. Cox 2005-01-10 10:02:04 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.

Derry needs this fix.  See pensacola BZ 133115 for patch.
