CVE-2008-2812 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-2812):
  The Linux kernel before 2.6.25.10 does not properly perform tty operations,
  which allows local users to cause a denial of service (system crash) or
  possibly gain privileges via vectors involving NULL pointer dereference of
  function pointers in (1) hamradio/6pack.c, (2) hamradio/mkiss.c, (3)
  irda/irtty-sir.c, (4) ppp_async.c, (5) ppp_synctty.c, (6) slip.c, (7)
  wan/x25_asy.c, and (8) wireless/strip.c in drivers/net/.

hardened-kernel unaffected at present time. Removing alias.

PS: Anything using >=genpatches-2.6.25-8 is unaffected
