Title: Gibraltar patches Solaris servers
Source: Network World Fusion
Date Written: June 6, 2003
Date Collected: June 9, 2003
On June 6, 2003, Gibraltar Software announced that the new version of its Everguard Site Server (version 2.2) now also supports remote patch deployment on Solaris servers, in addition to Windows and Linux servers that were already covered. With the number of security patches issued each year constantly increasing, the new appliance could be useful as it helps "administrators discover and track patches using a single toolkit," allows high-risk servers to be patched first, and "generates an inoculation record that shows a history of patch activity for any server."

According to Oracle Corp. officials at the Gartner IT Security Summit, as part of the company's new security push, Oracle plans to release several free security tools in the coming months to help customers find security vulnerabilities and protect systems. Among the new security tools, Oracle will make available security scanners to help customers identify which systems need security patches and software updates, and an "auto-hardening tool" to highlight unnecessary services and common configuration mistakes.

On June 9, 2003, Apple Computer issued a warning and patch to users highlighting two new security vulnerabilities in the file-sharing server software and the directory-services software provided with the Mac OS X Server operating system (OS). "When the server shares files that use the network file system (NFS) or the Unix file system (UFS) through the Apple File Service, a flaw could allow a remote user to overwrite arbitrary files," according to Apple. Log-in attempts to the server's directory services could result in passwords being sent back unencrypted.

Security experts claim to have discovered a yet-unnamed "third generation Trojan horse" program that appears to be infecting systems on the Internet.
Chris Hovis, director of product marketing for Lancope Inc., said that the new Trojan was first identified in May 2003 by a security analyst for a Defense Department contractor, and that both the FBI and the CERT Coordination Center at Carnegie Mellon University had been notified of the threat. The new Trojan listens for specific types of packets that "are believed to contain encrypted instructions for communicating with controllers," but the purpose of the Trojan and the extent of the problem remain unclear.

Title: IDS: What Lies Ahead?

Date Collected: June 12, 2003
Research firm Gartner Inc. caused a stir on June 11, 2003 by claiming that intrusion detection systems (IDS) are outdated and security investments should focus on firewalls instead. The report, which is part of Gartner's Information Security Hype Cycle, argues that: "Intrusion detection systems are a market failure and vendors are now hyping intrusion prevention systems, which have also stalled in the marketplace." Some IDS vendors are disturbed by Gartner's assessment. They claim that IDSs play a crucial role in a 'defense in-depth' security strategy. Gartner on the other hand believes they "will be obsolete by 2005."

Title: Reality Check: How Safe Is Linux?
Source: NewsFactor
Date Written: June 11, 2003
Date Collected: June 12, 2003
The article discusses the security of Linux operating systems (OSs), particularly in comparison with Microsoft Windows OSs. The author finds that any system or network can be made secure if security policies and technologies are applied. Linux networks can run into security difficulties, however, because the management and configuration of Linux is quite complex, and security flaws, such as privilege escalation, can be introduced through programming errors in programs included in Linux distributions. According to Dave Wreski, CEO of Linux distributor Guardian Digital, "Information leaks, unauthorized access, and buffer overflows are problem areas for Linux." In the past, Linux systems have also been exploited using insecure daemons like Sendmail, Telnet, FTP, and Samba. However, all these factors don't make Linux systems less secure than proprietary OSs, especially since Linux flaws are often discovered earlier and patched quicker.

Title: Spam virus 'hijacks' computers

Security experts are warning that spammers have started using viruses and Trojan horse programs to take control of machines that they then use to send out unsolicited and often fraudulent e-mails. UK-based e-mail security firm MessageLabs last week discovered the AVF virus, which is believed to be the first example of malware sent out by a spammer in order to disseminate his offerings anonymously. In contrast to other viruses, spam viruses don't try to spread rapidly, instead they open a secret back door in vulnerable computers for the purpose of sending out spam messages. Some security experts fear that spam viruses could make the rising tide of spam even worse, potentially overwhelming the entire Internet system.

On June 12, 2003, the Standards Board Review Committee of the Institute of Electrical and Electronics Engineers (IEEE) approved the new 802.11g standard for wireless local area networks (LANs) after a complicated three-year standardization process. The new standard sets requirements for wireless LAN equipment that will have to meet a carrying capacity of 24Mbps to 54Mbps in the 2.4GHz radio spectrum range. Wireless LAN gear under the new standard will still have to be backward compatible with existing 802.11b equipment.

Security firm Network Associates issued an advisory on June 12, 2003 warning users that a flaw in its McAfee GroupShield 5.2 anti-virus software for Microsoft Exchange 2000 servers could cause the servers to crash. Network Associates had issued a patch to fix the vulnerability in January 2003, but was forced to release a new advisory because at least four customers have been affected by the problem in the past two days. The latest incidents may be the result of a targeted attack aimed at exploiting the flaw, or due to spam e-mails that may have inadvertently triggered the flaw, according to Vincent Gullotto, vice president for Network Associates' anti-virus emergency response team. Customers are advised to apply the latest fix as soon as possible or potentially face lengthy e-mail outages.

Nokia has issued a statement warning customers that Nokia GGSN (Gateway GPRS support node) release 1 contains a vulnerability in the TCP stack that could allow a malicious attacker to launch a denial of service (DoS) strike using a computer and a mobile phone. By sending a malformed IP packet, an attacker could "crash all data connectivity within a GPRS based network." Security firm @stake notified Nokia of the flaw and both companies are working together to resolve the problem. Nokia has issued a software update (GGSN release 2) that is not at risk from the flaw.
