| Description: | Description:
The remote host is missing an update to linux-source-2.6.15
announced via advisory USN-508-1.
A security issue affects the following Ubuntu releases:
Ubuntu 6.06 LTS
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
Details follow:
A buffer overflow was discovered in the Moxa serial driver. Local
attackers could execute arbitrary code and gain root privileges.
(CVE-2005-0504)
A flaw was discovered in the IPv6 stack's handling of type 0 route headers.
By sending a specially crafted IPv6 packet, a remote attacker could cause
a denial of service between two IPv6 hosts. (CVE-2007-2242)
A flaw in the sysfs_readdir function allowed a local user to cause a
denial of service by dereferencing a NULL pointer. (CVE-2007-3104)
A buffer overflow was discovered in the random number generator. In
environments with granular assignment of root privileges, a local attacker
could gain additional privileges. (CVE-2007-3105)
It was discovered that certain setuid-root processes did not correctly
reset process death signal handlers. A local user could manipulate this
to send signals to processes they would not normally have access to.
(CVE-2007-3848)
It was discovered that the aacraid SCSI driver did not correctly check
permissions on certain ioctls. A local attacker could cause a denial
of service or gain privileges. (CVE-2007-4308)
Solution:
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 6.06 LTS:
linux-image-2.6.15-29-* 2.6.15-29.58
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.
