CVE-2009-3043
Description
From CVE.org
The tty_ldisc_hangup function in drivers/char/tty_ldisc.c in the Linux kernel 2.6.31-rc before 2.6.31-rc8 allows local users to cause a denial of service (system crash, sometimes preceded by a NULL pointer dereference) or possibly gain privileges via certain pseudo-terminal I/O activity, as demonstrated by KernelTtyTest.c.
Statement
Not vulnerable. This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 3, 4, 5 or Red Hat Enterprise MRG, as they do not contain a backport of the tty ldisc rewrite (upstream commits 65b770468e98 and cbe9352fa08f).
