Description :

Georgi Guninski discovered two Denial of Service vulnerabilities in
the Linux kernel.

An integer overflow in the vc_resize() function caused the memory
allocation for the new screen being too short, thus causing a buffer
overflow and a kernel crash.

There was also a memory leak in the ip_options_get() function. Calling
ip_cmsg_send() very often would gradually exhaust memory.

Note: The original advisory (see URL above) also mentions a
"ip_options_get integer overflow". This was already fixed in USN-38-1
(known as CVE-2004-1016).

Solution :

Upgrade to :
- linux-doc-2.6.8.1-2.6.8.1-16.5 (Ubuntu 4.10)
- linux-headers-2.6.8.1-4-2.6.8.1-16.5 (Ubuntu 4.10)
- linux-headers-2.6.8.1-4-386-2.6.8.1-16.5 (Ubuntu 4.10)
- linux-headers-2.6.8.1-4-686-2.6.8.1-16.5 (Ubuntu 4.10)
- linux-headers-2.6.8.1-4-686-smp-2.6.8.1-16.5 (Ubuntu 4.10)
- linux-headers-2.6.8.1-4-amd64-generic-2.6.8.1-16.5 (Ubuntu 4.10)
- linux-headers-2.6.8.1-4-amd64-k8-2.6.8.1-16.5 (Ubuntu 4.10)
- linux-headers-2.6.8.1-4-amd64-k8-smp-2.6.8.1-16.5 (Ubuntu 4.10)
