CVE-2008-2750 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-2750):
  The pppol2tp_recvmsg function in drivers/net/pppol2tp.c in the Linux kernel
  2.6 before 2.6.26-rc6 allows remote attackers to cause a denial of service
  (kernel heap memory corruption and system crash) and possibly have
  unspecified other impact via a crafted PPPOL2TP packet that results in a
  large value for a certain length variable.

hardened-kernel unaffected at present time. Removing alias.

PS: Anything using >=genpatches-2.6.25-10 is unaffected
