openSUSE 10 Security Update : kernel (kernel-4487)

This script is Copyright (C) 2007-2016 Tenable Network Security, Inc.

Synopsis :

The remote openSUSE host is missing a security update.

Description :

This kernel update fixes the following security problems :

- CVE-2007-3105: Stack-based buffer overflow in the random
number generator (RNG) implementation in the Linux
kernel before 2.6.22 might allow local root users to
cause a denial of service or gain privileges by setting
the default wake-up threshold to a value greater than
the output pool size, which triggers writing random
numbers to the stack by the pool transfer function
involving 'bound check ordering'. Since this value can
only be changed by a root user, exploitability is low.

- CVE-2007-2525: A memory leak in the PPPoE driver can be
abused by local users to cause a denial-of-service

- CVE-2007-3851: On machines with a Intel i965 based
graphics card local users with access to the direct
rendering devicenode could overwrite memory on the
machine and so gain root privileges.

- CVE-2007-4573: It was possible for local user to become
root by exploitable a bug in the IA32 system call
emulation. This affects x86_64 platforms with kernel
2.4.x and 2.6.x before only.

- CVE-2007-4571: An information disclosure vulnerability
in the ALSA driver can be exploited by local users to
read sensitive data from the kernel memory.
