RealNetworks Helix Universal Server 9.0.2 for Linux and 9.0.3 for Windows allows remote attackers to cause a denial of service (CPU and memory exhaustion) via a POST request with a Content-Length header set to -1. The problem surrounds the mishandling of some POST headers values. An attacker can exploit this issue to cause the affected server to consume excessive computer resources and hang, denying service to legitimate users. BACKGROUND RealNetworks Helix Universal Server is a universal digital media delivery platform with industry leading performance, integrated content distribution and Web services support. More information is available at http://www.realnetworks.com. II. The problem specifically exists in the handling of specially crafted POST requests. Generating a request with the Content-Length header set to -1 triggers an integer handling error resulting in mass utilization of memory and CPU time. III. ANALYSIS Any unauthenticated remote attacker can exploit this vulnerability, which causes the affected system to utilize mass amounts of memory and CPU time. The system will no longer be able to process future requests. The affected server must be restarted in order to resume normal functionality. IV. DETECTION iDEFENSE has confirmed the existence of this vulnerability in RealNetworks Helix Server version 9.0.2 for Linux and version 9.0.3 for Windows. It is suspected that earlier versions on both platforms are vulnerable as well. V. WORKAROUND Usage of an inline application level filter can help mitigate risk of exploitation by scanning for and filtering invalid Content-Length parameters. VI. VENDOR RESPONSE "Customers are encouraged to upgrade their Server software to the latest version, which contains a security patch." RealNetworks has released binaries that guard against the described vulnerability. The related advisory from RealNetworks is available at: http://service.real.com/help/faq/security/security100704.html VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CAN-2004-0774 to this issue.

Buffer overflow in digestmd5.c CVS release 1.170 (also referred to as digestmda5.c), as used in the DIGEST-MD5 SASL plugin for Cyrus-SASL but not in any official releases, allows remote attackers to execute arbitrary code. Cyrus SASL is affected by multiple critical vulnerabilities that may be remotely exploitable. The first issue is due to a boundary condition error, the second issue is due to a failure of the application to properly handle environment variables. Information currently available regarding these issues is insufficient to provide a more detailed analysis. This BID will be updated and split into separate BIDs when more information becomes available. An attacker can leverage the boundary condition issue to exploit arbitrary code on the affected computer. The impact of the environment variable issue is currently unknown. Cyrus SASL provides several open source implementations for security authentication. Cyrus SASL incorrectly handles the SASL_PATH environment variable, which could be exploited by a local attacker for privilege escalation attacks. Attackers can use the SASL_PATH environment variable to make privileged applications load arbitrary library files from any directory specified by the user, which can cause malicious programs to run with high privileges

Symantec Norton AntiVirus 2004, and earlier versions, allows a virus or other malicious code to avoid detection or cause a denial of service (application crash) using a filename containing an MS-DOS device name. Norton AntiVirus is affected by a scan evasion vulnerability when handling files with MS-DOS reserve device names. This issue is due to a design error that allows the files to avoid being scanned. It should be noted that this vulnerability only arises once the file is already present on a vulnerable computer. All Norton AntiVirus products are able to detect malicious files through incoming email. BACKGROUND Symantec's Norton AntiVirus protects email, instant messages, and other files by automatically removing viruses, worms, and Trojan horses. More information about the product is available from http://www.symantec.com II. The problem specifically exists in attempts to scan files and directories named as reserved MS-DOS devices. Reserved MS-DOS device names are a hold over from the original days of Microsoft DOS. The reserved MS-DOS device names represent devices such as the first printer port (LPT1) and the first serial communication port (COM1). Sample reserved MS-DOS device names include AUX, CON, PRN, COM1 and LPT1. reserved device names can be creating with standard Windows utilities by specifying the full Universal Naming Convention (UNC) path. The following command will successfully copy a file to the reserved device name 'aux' on the C:\ drive: copy source \\.\C:\aux III. ANALYSIS Exploitation allows attackers to evade detection of malicious code. Attackers can unpack or decode an otherwise detected malicious payload in a stealth manner. IV. DETECTION iDEFENSE has confirmed the existence of this vulnerability in the latest version of Norton AntiVirus. It is reported that earlier versions crash upon parsing files or directories using reserved MS-DOS device names. V. WORKAROUND Ensure that no local files or directories using reserved MS-DOS device names exist. On most modern Windows systems there should be no reserved MS-DOS device names present. While the Windows search utility can be used to locate offending files and directories, either a seperate tool or the specification of Universal Naming Convention (UNC) must be used to remote them. The following command will successfully remove a file stored on the C:\ drive named 'aux': del \\.\C:\aux VI. VENDOR RESPONSE "Symantec engineers have developed a fix for this issue for Symantec Norton AntiVirus 2004 that is currently available through LiveUpdate. The fix is being incorporated into all other supported Symantec Norton AntiVirus versions and will be available through LiveUpdate when fully tested and released." More information is available in Symantec Security Advisory SYM04-015. VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the names CAN-2004-0920 to these issues. This is a candidate for inclusion in the CVE list (http://cve.mitre.org), which standardizes names for security problems. VIII.

ServerAdmin in Mac OS X 10.2.8 through 10.3.5 uses the same example self-signed certificate on each system, which allows remote attackers to decrypt sessions. Multiple security vulnerabilities are reported in Mac OS X. A security update is available to address these issues and to provide other enhancements. The following issues are reported: Apple AFP server is reported prone to a remote denial of service vulnerability. A weak permissions vulnerability is reported to affect the AFP server. This may result in a false sense of security for an administrator. A vulnerability is reported to exist in the NetInfoManager utility. It is reported that the utility will, under certain circumstances, report the status of certain accounts as disabled when they are not. A heap-based buffer overrun is reported to exist in the QuickTime utility. An attacker may exploit this vulnerability to execute arbitrary instructions in the context of the user that is running the vulnerable software. Finally, ServerAdmin is reported prone to a weak default configuration vulnerability. This may result in ServerAdmin traffic being intercepted and decrypted by a remote attacker. This vulnerability has been split into BID 11344. Some of these issues may already be described in previous BIDs. This BID will be split up into unique BIDs when further analysis of this update is complete. This vulnerability allows attackers to decrypt all communications between ServerAdmin servers and clients. This facilitates the theft of authentication credentials by sniffing networks containing the affected application, and then utilizing the known private key in applications such as 'ssldump'. Once authentication credentials are stolen, attackers can then utilize ServerAdmin for full system compromise. Previous versions may also be affected

AFP Server on Mac OS X 10.3.x to 10.3.5, when a guest has mounted an AFP volume, allows the guest to "terminate authenticated user mounts" via modified SessionDestroy packets.

The der_chop script in the openssl package in Trustix Secure Linux 1.5 through 2.1 and other operating systems allows local users to overwrite files via a symlink attack on temporary files. A flaw in the OpenSSL library could allow a remote attacker to cause a denial of service on an affected application. A buffer overflow in certain Apple AirPort drivers may allow an attacker to execute arbitrary code with system privileges, or create a denial-of-service condition. Multiple RSA implementations fail to properly handle RSA signatures. This vulnerability may allow an attacker to forge RSA signatures. OpenSSL include der_chop The script contains a flaw that creates a temporary file in an inappropriate way for security reasons, so there is a vulnerability that is subject to symbolic link attacks.der_chop An arbitrary file may be created or overwritten with the privileges of the user executing the script. OpenSSL is affected by an insecure temporary file creation vulnerability. This issue is likely due to a design error that causes the application to fail to verify the existence of a file before writing to it. An attacker may leverage this issue to overwrite arbitrary files with the privileges of an unsuspecting user that activates the vulnerable application. Reportedly this issue is unlikely to facilitate privilege escalation. OpenSSL is an open source SSL suite. ---------------------------------------------------------------------- To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German.

An attacker may leverage this issue to cause the affected device to crash, denying service to legitimate users

Motorola Wireless Router WR850G running firmware 4.03 allows remote attackers to bypass authentication, log on as an administrator, and obtain sensitive information by repeatedly making an HTTP request for ver.asp until an administrator logs on. Motorola WR850G is a wireless router.  The attacker gains access to the WEB interface through periodic access restricted 'ver.asp' scripts, and can obtain the WEB interface user name and password. Using this password, by accessing frame_debug.asp, the WEB SHELL can be obtained and executed on the system. Any command. This issue is caused by a design error and may allow an attacker to ultimately take complete control over the device. Motorola wireless router WR850G running firmware version 4.03 is reportedly affected by this issue. It is possible that other models and firmware versions are affected as well

Symantec Enterprise Firewall/VPN Appliances 100, 200, and 200R running firmware before 1.63 allow remote attackers to cause a denial of service (device freeze) via a fast UDP port scan on the WAN interface. These issues are due to a failure of the application to handle exceptional conditions, a default configuration issue exists as well. An attacker can leverage a denial of service issue to cause the affected appliance to stop responding, requiring a power off to bring the device back to functionality. A filter bypass issue allows an attacker to bypass the filters on the 'tftpd', 'snmpd', and 'isakmp' services. An attacker can also read and write the community string of the affected device by default, facilitating disclosure and altering of the device's settings. Symantec Nexland legacy firewall appliances are also affected by these issues. Symantec Enterprise Firewall/VPN is an enterprise-level firewall/VPN system. Symantec Enterprise Firewall/VPN has a default public string, and remote attackers can use this value to obtain sensitive information or perform some configuration operations.
