Summary of Security Items from July 6 through July 20, 2004
The CISA Vulnerability Bulletin provides a summary of new vulnerabilities that have been recorded in the past week. In some cases, the vulnerabilities in the bulletin may not yet have assigned CVSS scores.
Vulnerabilities are based on the Common Vulnerabilities and Exposures (CVE) vulnerability naming standard and are organized according to severity, determined by the Common Vulnerability Scoring System (CVSS) standard. The division of high, medium, and low severities correspond to the following scores:
- High: vulnerabilities with a CVSS base score of 7.0–10.0
- Medium: vulnerabilities with a CVSS base score of 4.0–6.9
- Low: vulnerabilities with a CVSS base score of 0.0–3.9
Entries may include additional information provided by organizations and efforts sponsored by CISA. This information may include identifying information, values, definitions, and related links. Patch information is provided when available. Please note that some of the information in the bulletin is compiled from external, open-source reports and is not a direct result of CISA analysis.
This bulletin provides a summary of new or updated vulnerabilities, exploits, trends and viruses identified between
July 6 and July 20, 2004.
Bugs,
Holes, & Patches
The table below
summarizes vulnerabilities that have been identified, even if they
are not being exploited. Updates to items appearing in previous
bulletins are listed in bold. Complete details about patches or
workarounds are available from the source of the information or from the URL provided in the
section. CVE numbers are listed where applicable.
Note: All the information included in the
following tables has been discussed in newsgroups and
on web sites.
Risk is defined as follows:
- High - A high-risk
vulnerability is defined as one that will allow an intruder to immediately
gain privileged access (e.g., sysadmin or root) to the system or allow an
intruder to execute code or alter arbitrary system files. An example of a
high-risk vulnerability is one that allows an unauthorized user to send a
sequence of instructions to a machine and the machine responds with a command
prompt with administrator privileges. - Medium - A
medium-risk vulnerability is defined as one that will allow an intruder immediate
access to a system with less than privileged access. Such vulnerability will
allow the intruder the opportunity to continue the attempt to gain privileged
access. An example of medium-risk vulnerability is a server configuration
error that allows an intruder to capture the password file. - Low - A low-risk
vulnerability is defined as one that will provide information to an intruder
that could lead to further compromise attempts or a Denial of Service (DoS)
attack. It should be noted that while the DoS attack is deemed low from a
threat potential, the frequency of this type of attack is very high. DoS attacks
against mission-critical nodes are not included in this rating and any attack
of this nature should instead be considered to be a "High" threat.

| Adobe
Adobe Acrobat Reader version 6.0.1 | A buffer overflow vulnerability exists that allows remote attackers to execute arbitrary code. The problem specifically exists within a routine that is responsible for splitting the filename path into multiple components. Successful exploitation allows an attacker to execute arbitrary code under the privileges of the local user. Remote exploitation is possible by sending a specially crafted e-mail and attaching the malicious PDF document.
Update to the latest release of Adobe Acrobat and the free Adobe Reader, version 6.0.2 available at: http://www.adobe.com/support/techdocs/34222.htm Currently, we are not aware of any exploits for this vulnerability. | Adobe Reader 6.0 Filename Handler Buffer Overflow Vulnerability

Trends
Microsoft has released a Security Bulletin Summary for July 2004. This summary addresses vulnerabilities in various Windows applications and components. Exploitation of some of these vulnerabilities can result in the remote execution of arbitrary code by a remote attacker. For more information, see TA04-196A located at: http://www.us-cert.gov/cas/techalerts/TA04-196A.html
Six months since the W32/Bagle mass-mailing virus first appeared on the Internet, US-CERT continues to see new variants appearing and many variants (new and old) continuing to spread. Many variants of W32/Beagle are known to open a backdoor on an infected system which can lead to further exploitation by remote attackers.
US-CERT strongly encourages users to install and maintain anti-virus software and exercise caution when handling attachments. Anti-virus software may not be able to scan password protected archive files so users must use discretion when opening archive files and should scan files once extracted from an archive.
Viruses/Trojans
Top 10 High Threat Viruses
A list of high threat viruses, as reported to various anti-virus vendors and virus incident reporting organizations, has been ranked and categorized in the table below. For the purposes of collecting and collating data, infections involving multiple systems at a single location are considered a single infection. It is therefore possible that a virus has infected hundreds of machines but has only been counted once. With the number of viruses that appear each month, it is possible that a new virus will become widely distributed before the next edition of this publication. To limit the possibility of infection, readers are reminded to update their anti-virus packages as soon as updates become available. The table lists the viruses by ranking (number of sites affected), common virus name, type of virus code (i.e., boot, file, macro, multi-partite, script), trends (based on number of infections reported during the latest three months), and approximate date first found.
| Rank | Common Name | Type of Code | Trends | Date |
1 | W32/Netsky-P | Win32 Worm | Increase | March 2004 |
2 | W32/Zafi-B | Win32 Worm | New to Table | June 2004 |
3 | W32/Netsky-Z | Win32 Worm | Increase | April 2004 |
4 | W32/Bagle-AA | Win32 Worm | New to Table | April 2004 |
5 | W32/Netsky-D | Win32 Worm | Decrease | March 2004 |
6 | W32/Netsky-B | Win32 Worm | Decrease | February 2004 |
7 | W32/Netsky-Q | Win32 Worm | Decrease | March 2004 |
8 | W32/Sasser | Win32 Worm | Slight Increase | April 2004 |
9 | Bagle.AD | Win32 Worm | Decrease | April 2004 |
10 | Lovgate.AB | Win32 Worm | New to Table | May 2004 |
10 | TROJ_AGENT.AC | Trojan | New to Table | July 2004 |
New Viruses / Trojans
Viruses or Trojans Considered to be a High Level of Threat
- Atak.A - Atak.A is a mass e-mailing worm that hides by going to sleep when it suspects that antivirus software is trying to detect it. This worm had received a lot of media attention and while it is not considered a serious threat, it can generate a significant amount of spam.
- Bagle / Beagle - New variants of the Bagle virus appeared over the last two weeks. Infected PCs download a Trojan which can use the infected computer to distribute spam and other malware and to launch distributed denial-of-service attacks.
- WinCE.Duts.A: While not considered a high threat, this virus is the first virus reported for the Windows CE (Pocket PC) platform. The virus is a simple appending file infector and will only infect ARM-based devices.
The following table provides, in alphabetical order, a list of new viruses, variations of previously encountered viruses, and Trojans that have been discovered during the period covered by this bulletin. This information has been compiled from the following anti-virus vendors and security related web sites: Sophos, Trend Micro, Symantec, McAfee, Network Associates, Central Command, F-Secure, Kaspersky Labs, MessageLabs, and The WildList Organization International. Users should keep anti-virus software up to date and should contact their anti-virus vendors to obtain specific information on the Trojans and Trojan variants that anti-virus software detects.
NOTE: At times, viruses and Trojans may contain names or content that may be considered offensive.
