Security
Many people interested in security issues fear the first big security
breach which
affects mobile wireless devices. A large, destructive cell phone worm would
make for a bad day in many quarters. The "Mosquitos" trojan does not quite
live up to those fears, but there are lessons to be learned from it anyway.
Mosquitos is a game for Symbian-based wireless handsets. According to
early reports, a version of the game had been "cracked" and circulated
through the usual channels. Users who picked it up and ran it found out,
sooner or later, that it had a bad habit of sending text messages to
expensive, premium phone numbers. That was almost certainly not the
experience the users had in mind when they loaded the game.
While many outlets reported the existence of a Symbian trojan, rather fewer
followed up with the truth of the matter became clear: the "trojan"
functionality was an intentional feature added by the manufacturer of the
game. It is, in essence, an attempt at a copy protection mechanism; if the
game finds itself running outside of its intended geographical area, it
sends a bunch of expensive messages in retaliation. This behavior is a
feature, not a trojan.
Then again, that might depend on your definition of "trojan." It is an
undocumented behavior hidden within a program; certainly nobody who bought
this game intended to purchase a function which sends unwanted messages if
it decides things are not right. Most users might be forgiven for feeling
that they had, indeed, been trojaned after all.
It would be out of character for us to fail to point out that this sort of
behavior is almost exclusively associated with closed-source, proprietary
software. The author of a free software program is certainly capable of
inserting trojan-like behavior; consider the
mICQ incident from February, 2003. But it would be surprising indeed
for any such code to last for long. Free software means that hostile code
can be found and ripped out in a hurry. Now if we only had mobile phones built with
free software...

Brief items
News.com reports from Crypto 2004, where researchers are presenting findings on weaknesses in secure hash algorithms.
" Biham's presentation was very preliminary, but it could call into question the long-term future of the wildly popular SHA-1 algorithm and spur researchers to identify alternatives.
Currently considered the gold standard of its class of algorithms, SHA-1 is embedded in popular programs like PGP and SSL. It is certified by the National Institute of Standards and Technology and is the only signing algorithm approved for use in the U.S. government's Digital Signature Standard."

New vulnerabilities
acroread: UUDecode filename buffer overflow
| Package(s): | acroread |
CVE #(s): | |
| Created: | August 16, 2004 |
Updated: | August 17, 2004 |
| Description: |
acroread contains two errors in the handling of UUEncoded filenames.
First, it fails to check the length of a filename before copying it
into a fixed size buffer and, secondly, it fails to check for the
backtick shell metacharacter in the filename before executing a command
with a shell. By enticing a user to open a PDF with a specially crafted
filename, an attacker could execute arbitrary code or programs with the
permissions of the user running acroread. |

glibc: Information leak with LD_DEBUG

CVE #(s): | CAN-2004-1453

Updated: | May 26, 2005 |
| Description: |
Silvio Cesare discovered a potential information leak in glibc. It allows
LD_DEBUG on SUID binaries where it should not be allowed. This has various
security implications, which may be used to gain confidential information.
An attacker can gain the list of symbols a SUID application uses and their
locations and can then use a trojaned library taking precedence over those
symbols to gain information or perform further exploitation. |

xine-lib: VCD MRL buffer overflow

Updated: | August 18, 2004 |
| Description: |
xine-lib contains a bug where it is possible to overflow the vcd:// input
source identifier management buffer through carefully crafted playlists.
An attacker may construct a carefully-crafted playlist file which will
cause xine-lib to execute arbitrary code with the permissions of the
user. In order to conform with the generic naming standards of most
Unix-like systems, playlists can have extensions other than .asx (the
standard xine playlist format), and made to look like another file
(MP3, AVI, or MPEG for example). If an attacker crafts a playlist with
a valid header, they can insert a VCD playlist line that can cause a
buffer overflow and possible shellcode execution. |

Updated: | August 11, 2004 |
| Description: |
Javier Fernández-Sanguino Peña has discovered an exploitable
vulnerability in the way that Shorewall handles temporary files and
directories. The vulnerability can allow a non-root user to cause
arbitrary files on the system to be overwritten. LEAF Bering and Bering
uClibc users are generally not at risk due to the fact that LEAF boxes
do not typically allow logins by non-root users. The complete advisory is
here. |

The August issue of CRYPTO-GRAM is out; this months topics include another
stupid aviation security story, alibi networks, GHB, and phishing attacks.
" Computer security is an arms race, and money creates
very motivated attackers. Unsolved, this type of security problem can
change the way people interact with the Internet. It'll prove that the
naysayers were right all along, that the Internet isn't safe for
electronic commerce."
Full Story (comments: 5)
Version 2.2 of the Metasploit Framework is out; click below for the details. This release contains a set of new exploits, PPC and Sparc exploit support, and much more.
Full Story (comments: none)
vnunet has interviewed Robert Clyde, CTO at Symantec. " With open source, if an individual cares about a code flaw they'll fix it fast; if it's an obscure piece of code it could languish for years untouched. Commercial companies will try and fix all problems within a fixed timescale. Most commercial vendors are really behind reporting problems honestly and trying to fix them. I don't know of a single vendor who will sit on a vulnerability - maybe five years ago but not now."
Compare that with this eWeek article on Oracle's security performance. "It's been a good seven or eight months since the vulnerabilities were discovered. Sure, eight months seems like it would be 'as quickly as possible.' For a roomful of monkeys arbitrarily hitting keys to come up with a security fix. On broken keyboards."
