Description Flags
Backport proc_pid_cmdline() fix from RHEL3. none

Description Josh Bressers 2004-09-21 19:09:53 UTC
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 15:01:07 UTC
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 23:25:35 UTC
It looks like this was corrected for RHEL3, but RHEL21 is still vulnerable.

Comment 4 Don Howard 2005-09-15 23:28:19 UTC

Backport proc_pid_cmdline() fix from RHEL3.
