Test ID:1.3.6.1.4.1.25623.1.0.53867
Category:Ubuntu Local Security Checks
Title:Ubuntu USN-143-1 (linux-source-2.6.8.1)
Summary:Ubuntu USN-143-1 (linux-source-2.6.8.1)
Description:
The remote host is missing an update to linux-source-2.6.8.1
announced via advisory USN-143-1.

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)

The following packages are affected:

linux-image-2.6.8.1-5-power4
linux-image-2.6.8.1-5-power4-smp
linux-image-2.6.8.1-5-powerpc
linux-image-2.6.8.1-5-powerpc-smp
linux-image-2.6.10-5-amd64-generic
linux-image-2.6.10-5-amd64-k8
linux-image-2.6.10-5-amd64-k8-smp
linux-image-2.6.10-5-amd64-xeon
linux-patch-debian-2.6.8.1
linux-patch-ubuntu-2.6.10

A Denial of Service vulnerability has been discovered in the ptrace()
call on the amd64 platform. By calling ptrace() with specially crafted
(non-canonical) addresses, a local attacker could cause the kernel
to crash. This only affects the amd64 platform. (CVE-2005-1762)

ZouNanHai discovered that a local user could hang the kernel by
invoking syscall() with specially crafted arguments. This only affects
the amd64 platform when running in the 32 bit compatibility mode.
(CVE-2005-1765)

Solution:
The problem can be corrected by upgrading the affected package to
version 2.6.8.1-16.20 (for Ubuntu 4.10) and 2.6.10-34.3 (for Ubuntu
5.04). You need to reboot your computer after doing a standard system
upgrade to effect the necessary changes.
