| Description: | Description:
The remote host is missing an update to linux
announced via advisory USN-614-1.
A security issue affects the following Ubuntu releases:
Ubuntu 8.04 LTS
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
Details follow:
It was discovered that PowerPC kernels did not correctly handle reporting
certain system details. By requesting a specific set of information,
a local attacker could cause a system crash resulting in a denial
of service. (CVE-2007-6694)
A race condition was discovered between dnotify fcntl() and close() in
the kernel. If a local attacker performed malicious dnotify requests,
they could cause memory consumption leading to a denial of service,
or possibly send arbitrary signals to any process. (CVE-2008-1375)
On SMP systems, a race condition existed in fcntl(). Local attackers
could perform malicious locks, causing system crashes and leading to
a denial of service. (CVE-2008-1669)
The tehuti network driver did not correctly handle certain IO functions.
A local attacker could perform malicious requests to the driver,
potentially accessing kernel memory, leading to privilege escalation
or access to private system information. (CVE-2008-1675)
Solution:
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 8.04 LTS:
linux-image-2.6.24-18-386 2.6.24-18.32
linux-image-2.6.24-18-generic 2.6.24-18.32
linux-image-2.6.24-18-hppa32 2.6.24-18.32
linux-image-2.6.24-18-hppa64 2.6.24-18.32
linux-image-2.6.24-18-itanium 2.6.24-18.32
linux-image-2.6.24-18-lpia 2.6.24-18.32
linux-image-2.6.24-18-lpiacompat 2.6.24-18.32
linux-image-2.6.24-18-mckinley 2.6.24-18.32
linux-image-2.6.24-18-openvz 2.6.24-18.32
linux-image-2.6.24-18-powerpc 2.6.24-18.32
linux-image-2.6.24-18-powerpc-smp 2.6.24-18.32
linux-image-2.6.24-18-powerpc64-smp 2.6.24-18.32
linux-image-2.6.24-18-rt 2.6.24-18.32
linux-image-2.6.24-18-server 2.6.24-18.32
linux-image-2.6.24-18-sparc64 2.6.24-18.32
linux-image-2.6.24-18-sparc64-smp 2.6.24-18.32
linux-image-2.6.24-18-virtual 2.6.24-18.32
linux-image-2.6.24-18-xen 2.6.24-18.32
After a standard system upgrade you need to reboot your computer to
effect the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-386,
linux-powerpc, linux-amd64-generic), a standard system upgrade will
automatically perform this as well.
