service (crash). This issue is rated as having important security
impact (CVE-2005-0136).

A flaw was discovered in the servicing of a raw device ioctl. A local
user who has access to raw devices could use this flaw to write to
kernel memory and cause a denial of service or potentially gain
privileges. This issue is rated as having moderate security impact

A flaw in fragment forwarding was discovered that affected the
netfilter subsystem for certain network interface cards. A remote
attacker could send a set of bad fragments and cause a denial of
service (system crash). Acenic and SunGEM network interfaces were the
only adapters affected, which are in widespread use. (CVE-2005-0209)

A flaw in the futex functions was discovered affecting the Linux 2.6
