Security
March 8, 2006
This article was contributed by Jake Edge.
Elliptic Curve Cryptography (ECC) has been gaining momentum as a replacement
for RSA public key cryptography largely based on its efficiency, but also
because the US National Security Agency (NSA) included
it, while excluding RSA, from its
Suite
B cryptography recommendations. Suite B is a set of algorithms that the
NSA recommends for use in protecting both classified and unclassified
US government information and systems.
Public key cryptography is the basis for tools like ssh as well as Secure
Sockets Layer (SSL) for encrypting web traffic.
For readers who would like more information, a nice introduction to
public key
cryptography and the
RSA algorithm can be found on
Wikipedia.
ECC is based on some very deep
math
involving elliptic curves in a finite field. It relies on the difficulty
of solving the Elliptic Curve Discrete Logarithm Problem (ECDLP) in much
the same way that RSA depends on the difficulty of factoring the product
of two large primes. The best known method for solving
ECDLP is fully exponential, whereas the number field sieve (for factoring) is
sub-exponential. This allows ECC to use drastically smaller keys to provide
the equivalent security; a 160-bit ECC key is equivalent to a 1024-bit RSA key.
Smaller key sizes lead to faster processing, which is very interesting to
folks that are implementing encryption on small, mobile devices with limited
resources in terms of power, CPU and memory. It is also very desirable for
large web servers that will be handling many encrypted sessions. These are
the technical considerations driving adoption. The NSA's recommendation makes
it very attractive to companies that sell encryption products to the
government and many non-governmental entities will also want products
that implement ECC.
In order to use elliptic curves as part of a public key cryptosystem, both
parties must agree on a set of domain parameters that fully specify the curve
that is being used. Various groups, notably the US National Institute for
Standards and Technology (NIST) and the Standards for Efficient Cryptography
Group (SECG) have recommendations for the domain parameters to be used for
various key sizes. The Internet Engineering Task Force (IETF) also has a
draft
specification for adding ECC to SSL/TLS.
Sun Microsystems has donated ECC code to OpenSSL and the Network Security
Services (NSS) library; this allows the Apache web server and Mozilla browsers
(and many other programs) to use ECC.
Unfortunately, as with RSA before its patent expired, the ECC landscape is
littered with patent claims; some of dubious enforceability due to prior
art. Sun claims patents on ECC technology, but has provided a "patent peace"
provision in its license that states that it will not enforce its patent
claims and asks that anyone holding patents associated with the code not
enforce them against Sun.
The wild card in the ECC patent arena seems to
be Certicom which claims a large number of ECC patents and has not made a
clear statement of its intentions with regard to open source implementations.
The NSA licensed Certicom's patents for $25 million to allow them and their
suppliers to use ECC, lending some credence to at least some of the
Certicom patents.
Other companies also have
patents on various
pieces of ECC technology.
As is often the case with patents, it is well nigh impossible to determine
what the patents cover and if an implementation infringes without going to
court. Ironically, the clearest description of what is and is not patented
is an RSA Laboratories
FAQ entry:
In all of these cases, it is the implementation technique that is patented,
not the prime or representation, and there are alternative, compatible
implementation techniques that are not covered by the patents.
Of course, this is not legal advice from RSA and may or may not be how it
is interpreted by the courts. We will all have to wait and see how it
plays out if one or more of the patent holders decides to sue.

network devices. A local attacker could exploit this by opening any
file in /proc/sys/net/ipv4/conf/<interface>/ and waiting until that
interface was shut down. Under certain circumstances this could lead
to a kernel crash or even arbitrary code execution with full kernel
privileges. (CVE-2005-2709)
Tetsuo Handa discovered a local Denial of Service vulnerability in the
udp_v6_get_port() function. On computers which use IPv6, a local
attacker could exploit this to trigger an infinite loop in the kernel.
(CVE-2005-2973)
Harald Welte discovered a Denial of Service vulnerability in the USB
devio driver. A local attacker could exploit this by sending an "USB
Request Block" (URB) and terminating the sending process before the
arrival of the answer, which left an invalid pointer and caused a
kernel crash. (CVE-2005-3055)
Pavel Roskin discovered an information leak in the Orinoco wireless
card driver. When increasing the buffer length for storing data, the
buffer was not padded with zeros, which exposed a random part of the
system memory to the user. (CVE-2005-3180)
A resource leak has been discovered in the handling of POSIX timers in
the exec() function. This could be exploited to a Denial of Service
attack by a group of local users. (CVE-2005-3271)
Stephen Hemminger discovered a weakness in the network bridge driver.
Packets which had already been dropped by the packet filter could
poison the forwarding table, which could be exploited to make the
bridge forward spoofed packages. (CVE-2005-3272)
David S. Miller discovered a buffer overflow in the rose_rt_ioctl()
function. By calling the function with a large "ngidis" argument, a
local attacker could cause a kernel crash. (CVE-2005-3273)
Neil Horman discovered a race condition in the connection timer
handling. This allowed a local attacker to set up an expiration
handler which modified the connection list while the list still being
traversed, which could result in a kernel crash. This vulnerability
only affects multiprocessor (SMP) systems. (CVE-2005-3274)
Patrick McHardy noticed a logic error in the network address
translation (NAT) connection tracker. A remote attacker could exploit
this by causing two packets for the same protocol to be NATed at the
same time, which resulted in a kernel crash. (CVE-2005-3275)
Paolo Giarrusso discovered an information leak in the
sys_get_thread_area(). The returned structure was not properly
cleared, which exposed a small amount of kernel memory to userspace
programs. This could possibly expose confidential data.

| Created: | January 20, 2006 |
Updated: | April 18, 2006 |
| Description: |
Here's another set of vulnerabilities in the Linux kernel:
- A race condition in the 2.6 kernel could allow a local user to cause a
DoS by triggering a core dump in one thread while another thread has a
pending SIGSTOP (CVE-2005-3527).
- The ptrace functionality in 2.6 kernels prior to 2.6.14.2, using
CLONE_THREAD, does not use the thread group ID to check whether it is
attaching to itself, which could allow local users to cause a DoS
(CVE-2005-3783).
- The auto-reap child process in 2.6 kernels prior to 2.6.15 include
processes with ptrace attached, which leads to a dangling ptrace
reference and allows local users to cause a crash (CVE-2005-3784).
- A locking problem in the POSIX timer cleanup handling on exit on
kernels 2.6.10 to 2.6.14 when running on SMP systems, allows a local
user to cause a deadlock involving process CPU timers (CVE-2005-3805).
- The IPv6 flowlabel handling code in 2.4 and 2.6 kernels prior to
2.4.32 and 2.6.14 modifies the wrong variable in certain circumstances,
which allows local users to corrupt kernel memory or cause a crash by
triggering a free of non-allocated memory (CVE-2005-3806).
- An integer overflow in 2.6.14 and earlier could allow a local user to
cause a hang via 64-bit mmap calls that are not properly handled on a
32-bit system (CVE-2005-3808).

libgd2: buffer overflows in PNG handling
| Package(s): | libgd2 |
CVE #(s): | CAN-2004-0990
CAN-2004-0941
|
| Created: | October 29, 2004 |
Updated: | June 28, 2006 |
| Description: |
Several buffer overflows have been discovered in libgd's PNG handling
functions.
If an attacker tricked a user into loading a malicious PNG image, they
could leverage this into executing arbitrary code in the context of
the user opening image. Most importantly, this library is commonly
used in PHP. One possible target would be a PHP driven photo website
that lets users upload images. Therefore this vulnerability might lead
to privilege escalation to a web server's privileges.
Multiple buffer overflows in the gd graphics library (libgd) 2.0.21 and
earlier may allow remote attackers to execute arbitrary code via malformed
image files that trigger the overflows due to improper calls to the
gdMalloc function. |
