Unknown vulnerability in ScreenOS in Juniper Networks NetScreen firewall 3.x through 5.x allows remote attackers to cause a denial of service (device reboot or hang) via a crafted SSH v1 packet. A vulnerability in the SSHv1 service of NetScreen firewalls could allow an attacker to cause a denial-of-service condition. It is reported that the vulnerability may be triggered by a remote attacker, prior to any form of authentication. Netscreen is a firewall security solution, and its operating system is ScreenOS. The firewall will reboot or hang, stopping normal services

Heap-based buffer overflow in ASN.1 decoding library in Check Point VPN-1 products, when Aggressive Mode IKE is implemented, allows remote attackers to execute arbitrary code by initiating an IKE negotiation and then sending an IKE packet with malformed ASN.1 data. A vulnerability exists in Check Point's VPN-1 Server, which is included in many Check Point products. This vulnerability may permit a remote attacker to compromise the gateway system. This issue results from insufficient boundary checks performed by the application when processing user-supplied data. This overflow occurs during the initial key exchange process, and can be triggered with a single UDP packet. Since ISAKMP uses the UDP transport, a spoofed source address can be used in an attack. Check Point reports that for a single packet attack to succeed, VPN-1 must be configured for aggressive mode key exchange. Without aggressive mode, an attacker must initiate a real key negotiation session. This vulnerability can lead to remote code execution in the context of the VPN-1 process. This can lead to a complete system compromise

SQL injection vulnerability in index.php in the Search module for Php-Nuke allows remote attackers to execute arbitrary SQL statements via the instory parameter. PHP-Nuke is prone to a sql-injection vulnerability

The search module in Php-Nuke allows remote attackers to gain sensitive information via the (1) "**" or (2) "+" search patterns, which reveals the path in an error message. PHP-Nuke is prone to a information disclosure vulnerability. There is a vulnerability in Php-Nuke's search module

Multiple cross-site scripting vulnerabilities in index.php in the Search module for Php-Nuke allows remote attackers to inject arbitrary web script or HTML via the (1) sid, (2) max, (3) sel1, (4) sel2, (5) sel3, (6) sel4, (7) sel5, (8) match, (9) mod1, (10) mod2, or (11) mod3 parameters. PHP-Nuke is prone to a cross-site scripting vulnerability

Multiple SQL injection vulnerabilities in the Search module in Php-Nuke allow remote attackers to execute arbitrary SQL via the (1) min or (2) categ parameters. PHP-Nuke is prone to a sql-injection vulnerability

The HTTP server in Lexmark T522 and possibly other models allows remote attackers to cause a denial of service (server crash, reload, or hang) via an HTTP header with a long Host field, possibly triggering a buffer overflow. T522 Network Printer is prone to a denial-of-service vulnerability. The HTTP service program of the Lexmark printer does not process some HTTP requests correctly. Remote attackers can use this vulnerability to carry out a denial of service attack on the printer WEB service

The DSS verification code in Dropbear SSH Server before 0.43 frees uninitialized variables, which might allow remote attackers to gain access. Dropbear SSH is affected by an unspecified Digital Signal Standard (DSS) authentication vulnerability. The impact of this issue is currently unknown. Presumably, an attacker could use this issue to gain unauthorized access to a computer running the vulnerable application, but this is not confirmed. We will update this BID as more information emerges. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco Security Advisory: Cisco Unified IP Phone Overflow and Denial of Service Vulnerabilities Revision 1.0 For Public Release 2008 February 13 1600 UTC (GMT) +-------------------------------------------------------------------- Summary ======= Cisco Unified IP Phone models contain multiple overflow and denial of service (DoS) vulnerabilities.

Multiple versions of Cisco ONS 15327, ONS 15454, and ONS 15454 SDH, including 4.6(0) and 4.6(1), 4.5(x), 4.1(0) to 4.1(3), 4.0(0) to 4.0(2), and earlier versions, allows remote attackers to cause a denial of service (control card reset) via malformed (1) IP or (2) ICMP packets. A vulnerability exists in multiple control cards used by Cisco ONS devices. This vulnerability could allow a remote attacker to cause a denial-of-service condition. Most of the reported issues are related to handling of malformed packets, resulting in a denial of service condition. However, an authentication bypass vulnerability has also been reported to affect some platforms. Attackers can send malformed IP, ICMP, TCP and UDP packets to cause XTC, TCC/TCC+/TCC2 and TCCi/TCC2 control cards to reboot. Repeated issuance of these malformed packets can cause the control card to stop responding to normal services. The CSCee27329 (passwd) vulnerability is that if the account is set with an empty password, then the device can be successfully authenticated by using a password exceeding 10 characters to log in to the device. This vulnerability only affects the TL1 login interface. The CTC login interface is not affected by this vulnerability

The HTTP administration interface on Conceptronic CADSLR1 ADSL router running firmware 3.04n allows remote attackers to cause a denial of service (device reboot) via an HTTP request with a long username. The Conseptronic CADSLR1 router is reported to contain a denial of service vulnerability. This vulnerability reportedly presents itself in the embedded HTTP server used for web-based administration of the router. When presented a large malformed request, the device will reportedly crash and reboot. This vulnerability could be exploited by a remote attacker to deny service to legitimate users. Due to code reuse across products, other Conseptronic devices may also be vulnerable to similar issues. TITLE: Conceptronic CADSLR1 Router Denial of Service Vulnerability SECUNIA ADVISORY ID: SA12110 VERIFY ADVISORY: http://secunia.com/advisories/12110/ CRITICAL: Less critical IMPACT: DoS WHERE: >From local network OPERATING SYSTEM: Conceptronic CADSLR1 http://secunia.com/product/3707/ DESCRIPTION: Jordi Corrales has reported a vulnerability in CADSLR1, allowing malicious people to cause a Denial of Service. The problem is that the device fails to handle HTTP requests with a long username (65535 characters). This causes the device to reboot. This has been reported to affect devices running firmware version 3.04n. Prior versions may also be affected. SOLUTION: Filter access to the device or disable the HTTP service.

Multiple versions of Cisco ONS 15327, ONS 15454, and ONS 15454 SDH, including 4.1(0) to 4.1(2), 4.5(x), 4.0(0) to 4.0(2), and earlier versions, allows remote attackers to cause a denial of service (control card reset) via malformed SNMP packets. A vulnerability exists in multiple control cards used by Cisco ONS devices. This vulnerability could allow a remote attacker to cause a denial-of-service condition. Most of the reported issues are related to handling of malformed packets, resulting in a denial of service condition. However, an authentication bypass vulnerability has also been reported to affect some platforms. Attackers can send malformed IP, ICMP, TCP and UDP packets to cause XTC, TCC/TCC+/TCC2 and TCCi/TCC2 control cards to reboot. Repeated issuance of these malformed packets can cause the control card to stop responding to normal services. The CSCee27329 (passwd) vulnerability is that if the account is set with an empty password, then the device can be successfully authenticated by using a password exceeding 10 characters to log in to the device. This vulnerability only affects the TL1 login interface. The CTC login interface is not affected by this vulnerability

Multiple versions of Cisco ONS 15327, ONS 15454, and ONS 15454 SDH, including 4.6(0) and 4.6(1), 4.5(x), 4.1(0) to 4.1(3), 4.0(0) to 4.0(2), and earlier versions, allows remote attackers to cause a denial of service (control card reset) via a large number of TCP connections with an invalid response instead of the final ACK (TCP-ACK).

im-switch before 11.4-46.1 in Fedora Core 2 allows local users to overwrite arbitrary files via a symlink attack on the imswitcher[PID] temporary file. It is reported that im-switch is prone to a local insecure temporary file handling symbolic link vulnerability. The im-switch utility will write to this temporary file before verifying its existence; this would facilitate a symbolic link attack. An attacker may exploit this issue to corrupt arbitrary files. This corruption may potentially result in the elevation of privileges, or in a system wide denial of service. Fedora Core is a Linux system distributed by RedHat. \'\'/usr/bin/im-switch\'\'use \"/tmp/imswitcher$$\" as a temporary file, but because the /tmp/ directory is writable and $$(PID) can be cloud-registered, Therefore, attackers can use symbolic links to destroy important files in the system, which may cause privilege escalation

Buffer overflow in Microsoft Internet Information Server (IIS) 4.0 allows local users to execute arbitrary code via the redirect function. A buffer overflow vulnerability exists in the Portable Operating System Interface for UNIX (POSIX) subsystem for Windows NT 4.0 and Windows 2000. This vulnerability may be exploited by a local authenticated user to gain full system privileges. The Microsoft Windows 2000 Utility Manager allows authenticated local users to launch applications with SYSTEM privileges. Microsoft Windows contains a remote code execution vulnerability in the way that the Windows Shell launches applications. An remote attacker could exploit this vulnerability to execute arbitrary code if they could trick a user into visiting a malicious website. Microsoft IIS 4.0 is reported prone to a buffer overflow vulnerability when handling redirects. This could lead to complete compromise of an affected computer. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 National Cyber Alert System Technical Cyber Security Alert TA04-196A Multiple Vulnerabilities in Microsoft Windows Components and Outlook Express Original release date: July 14, 2004 Last revised: -- Source: US-CERT Systems Affected * Microsoft Windows Systems Overview Microsoft has released a Security Bulletin Summary for July, 2004. This summary includes several bulletins that address vulnerabilities in various Windows applications and components. Details of the vulnerabilities and their impacts are provided below. I. Description The table below provides a reference between Microsoft's Security Bulletins and the related US-CERT Vulnerability Notes. More information related to the vulnerabilities is available in these documents. The attacker would have to convince a victim to view an HTML document (web page, HTML email) or click on a crafted URI link. Exploitation of VU#869640 can lead to a denial-of-service condition against Outlook Express. III. Solution Apply a patch Microsoft has provided the patches for these vulnerabilities in the Security Bulletins and on Windows Update. Do not follow unsolicited links It is generally a good practice not to click on unsolicited URLs received in email, instant messages, web forums, or Internet relay chat (IRC) channels. However, this practice does not always prevent exploitation of these types vulnerabilities. For example, a trusted web site could be compromised and modified to deliver exploit script to unsuspecting clients. Maintain updated anti-virus software Anti-virus software with updated virus definitions may identify and prevent some exploit attempts, but variations of exploits or attack vectors may not be detected. Do not rely solely on anti-virus software to defend against these vulnerabilities. More information about viruses and anti-virus vendors is available on the US-CERT Computer Virus Resources page. Appendix A. Vendor Information Specific information about these issue are available in the Security Bulletin Summary for July, 2004 and the US-CERT Vulnerability Notes. Appendix B.
