Ubuntu 5.04 / 5.10 / 6.06 LTS : linux-source-2.6.10/-2.6.12/-2.6.15 vulnerabilities (USN-346-1)

Ubuntu Security Notice (C) 2006-2016 Canonical, Inc. / NASL script (C) 2007-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

A Denial of service vulnerability was reported in iptables' SCTP
conntrack module. On computers which use this iptables module, a
remote attacker could exploit this to trigger a kernel crash.
(CVE-2006-2934)

A buffer overflow has been discovered in the dvd_read_bca() function.
By inserting a specially crafted DVD, USB stick, or similar
automatically mounted removable device, a local user could crash the
machine or potentially even execute arbitrary code with full root
privileges. (CVE-2006-2935)

The ftdi_sio driver for serial USB ports did not limit the amount of
pending data to be written. A local user could exploit this to drain
all available kernel memory and thus render the system unusable.
(CVE-2006-2936)

James McKenzie discovered a Denial of Service vulnerability in the NFS
driver. When exporting an ext3 file system over NFS, a remote attacker
could exploit this to trigger a file system panic by sending a
specially crafted UDP packet. (CVE-2006-3468)

Wei Wang of McAfee Avert Labs discovered a buffer overflow in the
sctp_make_abort_user() function of iptables' SCTP module. On computers
which use this module, a local attacker could exploit this to execute
arbitrary code with root privileges. (CVE-2006-3745)

Olof Johansson discovered that the kernel did not disable the 'HID0'
bit on PowerPC 970 processors so that the ATTN instruction was
enabled. A local user could exploit this to crash the kernel. This
flaw only affects the powerpc architecture. (CVE-2006-4093)

The UDF file system does not handle extends larger than 1 GB, but did
not check for this restriction on truncating files. A local user could
exploit this to crash the kernel. (CVE-2006-4145).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 7.8
(CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:C)
CVSS Temporal Score : 6.8
(CVSS2#E:ND/RL:OF/RC:ND)
Public Exploit Available : false
