[USN-47-1] Linux kernel vulnerabilities

===========================================================
Ubuntu Security Notice USN-47-1           December 23, 2004
linux-source-2.6.8.1 vulnerabilities
http://lists.netsys.com/pipermail/full-disclosure/2004-December/030011.html
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

linux-image-2.6.8.1-4-386
linux-image-2.6.8.1-4-686
linux-image-2.6.8.1-4-686-smp
linux-image-2.6.8.1-4-amd64-generic
linux-image-2.6.8.1-4-amd64-k8
linux-image-2.6.8.1-4-amd64-k8-smp
linux-image-2.6.8.1-4-amd64-xeon
linux-image-2.6.8.1-4-k7
linux-image-2.6.8.1-4-k7-smp
linux-image-2.6.8.1-4-power3
linux-image-2.6.8.1-4-power3-smp
linux-image-2.6.8.1-4-power4
linux-image-2.6.8.1-4-power4-smp
linux-image-2.6.8.1-4-powerpc
linux-image-2.6.8.1-4-powerpc-smp

The problem can be corrected by upgrading the affected package to
version 2.6.8.1-16.5. You need to reboot the computer after doing a
standard system upgrade to effect the necessary changes.

Details follow:

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 CAN-2004-1016).
