Description Eugene Teo (Security Response) 2010-04-14 02:55:34 UTC
Description of problem:
release_one_tty(tty) can be called when tty still has a reference to pgrp/session. In this case we leak the pid.

Upstream commit:

Comment 6 Eugene Teo (Security Response) 2010-04-15 00:41:20 UTC
pgrp member in struct tty_struct was converted to struct pid in commit ab521dc0, so kernels of version v2.6.21-rc1 and above are affected by this. mrg-1 backported this patch.


This issue did not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 3, 4 and 5 as they did not include upstream commit ab521dc0 that introduced the problem. This issue was addressed in Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2010-0631.html.

Comment 8 errata-xmlrpc 2010-08-17 15:54:25 UTC
