The International Domain Name (IDN) support in Safari 1.2.5 allows remote attackers to spoof domain names using punycode encoded domain names that are decoded in URLs and SSL certificates in a way that uses homograph characters from other character sets, which facilitates phishing attacks. Multiple browsers are reported prone to vulnerabilities that surround the handling of International Domain Names. The vulnerabilities are caused by inconsistencies in how International Domain Names are processed. Reports indicate that attackers can leverage this to spoof address bars, status bars, and SSL certificate values. Remote attackers may exploit these vulnerabilities in phishing-style attacks. Through a false sense of trust, users may voluntarily disclose sensitive information to a malicious website. Although these vulnerabilities are reported to affect browsers, mail clients that depend on the browser to generate HTML code may also be affected. KDE is a free and open source X desktop management program for Linux and Unix workstations. Since version 3.2, KDE and its web browser Konqueror have supported International Domain Names (IDNs), which makes KDE vulnerable to a phishing technique called Homograph

The Finder in Mac OS X and earlier allows local users to overwrite arbitrary files and gain privileges by creating a hard link from the .DS_Store file to an arbitrary file. An insecure file creation vulnerability affects Apple Mac OS X Finder. This issue is due to a failure of the application to validate the existence of files prior to creating or writing to them. An attacker may leverage this issue to cause a system-wide denial of service or to gain escalated privileges on an affected computer, potentially leading to unauthorized superuser access.

Cisco Systems (Linksys) of psus4 printserver Exists in unspecified vulnerabilities.None. Linksys PSUS4 is an embedded linksys wireless print server.  Linksys PSUS4 has problems processing wireless HTTP requests. Remote attackers can use this vulnerability to conduct denial of service attacks. An attacker may exploit this condition to deny service to the affected PrintServer

Cisco IP/VC Videoconferencing System 3510, 3520, 3525 and 3530 contain hard-coded default SNMP community strings, which allows remote attackers to gain access, cause a denial of service, and modify configuration. A default community string vulnerability affects Cisco IP/VC Videoconferencing System devices. This issue is due to a design flaw where hard-coded community strings are stored on the device. This issue may be leveraged to gain unauthorized administrator access to affected devices. This would allow an attacker to create new services, terminate or affect existing sessions, and redirect traffic to a different destination, among other attacks

Ingate Firewall 4.1.3 and earlier does not terminate the PPTP session for an active user when the administrator disables that user from a resource, which could allow remote authenticated users to retain unauthorized access to resources. Ingate Firewall does not remove PPTP tunnels created by a user that has been disabled by the firewall administrator. Even if the user has been disabled, any PPTP tunnels they have created will persist

Cisco IOS 12.0S through 12.3YH allows remote attackers to cause a denial of service (device restart) via a crafted IPv6 packet. A denial-of-service vulnerability exists in Cisco's Internetwork Operating System (IOS). This vulnerability may allow attackers to conduct denial-of-service attacks on an affected device. Cisco IOS In IPv6 Physical and logical interfaces due to improper handling of packets (6to4 Tunnel ) At IPv6 If you have enabled multiple invalid IPv6 A vulnerability exists in which a device is restarted by interpreting a packet.System disrupted service operation (DoS) May be in a state. This issue is due to a failure of the affected operating system to properly handle specially crafted network data. It is possible for an attacker to produce a sustained denial of service condition against an affected device by continually sending the malicious network data. An attacker may leverage this issue to cause an affected device to reload, denying service to legitimate users. Cisco IOS is the operating system that runs on many Cisco devices. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Technical Cyber Security Alert TA05-026A Multiple Denial-of-Service Vulnerabilities in Cisco IOS Original release date: January 26, 2005 Last revised: -- Source: US-CERT Systems Affected * Cisco routers and switches running IOS in various configurations Overview Several denial-of-service vulnerabilities have been discovered in Cisco's Internet Operating System (IOS). I. Further details are available in the following vulnerability notes: VU#583638 - Cisco IOS contains DoS vulnerability in MPLS packet processing The IOS implementation of Multi Protocol Label Switching (MPLS) contains a vulnerability that allows malformed MPLS packets to cause an affected device to reload. An unauthenticated attacker can send these malformed packets on a local network segment that is connected to a vulnerable device interface. The vulnerability is exposed on both physical interfaces (i.e., hardware interfaces), and logical interfaces (i.e., software defined interfaces such as tunnels) that are configured for IPv6. VU#689326 - Cisco IOS vulnerable to DoS via malformed BGP packet An IOS device that is enabled for Border Gateway Protocol (BGP) and set up with the bgp log-neighbor-changes option is vulnerable to a denial-of-service attack via a malformed BGP packet. II. Repeated exploitation of these vulnerabilites would result in a sustained denial-of-service condition. Since devices running IOS may transit traffic for a number of other networks, the secondary impacts of a denial of service may be severe. III. Solution Upgrade to a fixed version of IOS Cisco has updated versions of its IOS software to address these vulnerabilities. Please refer to the "Software Versions and Fixes" sections of the Cisco Security Advisories listed in Appendix A for more information on upgrading. Workaround Cisco has also published practical workarounds for VU#689326 and VU#583638.

Cisco IOS 12.1T, 12.2, 12.2T, 12.3 and 12.3T, with Multi Protocol Label Switching (MPLS) installed but disabled, allows remote attackers to cause a denial of service (device reload) via a crafted packet sent to the disabled interface. A denial-of-service vulnerability exists in Cisco's Internetwork Operating System (IOS). This vulnerability may allow attackers to conduct denial-of-service attacks on an affected device. A vulnerability in the way Cisco IOS handles IPv6 packets could result in a remotely exploitable denial of service. It is reported that the vulnerability presents itself when an affected router handles an unspecified malicious packet on a MPLS disabled interface. A remote attacker that resides on the same network segment as the vulnerable router may exploit this vulnerability continuously to effectively deny network-based services to legitimate users. Cisco IOS is the operating system that runs on many Cisco devices. There is a problem in the processing of special MPLS packets in Cisco IOS devices. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Technical Cyber Security Alert TA05-026A Multiple Denial-of-Service Vulnerabilities in Cisco IOS Original release date: January 26, 2005 Last revised: -- Source: US-CERT Systems Affected * Cisco routers and switches running IOS in various configurations Overview Several denial-of-service vulnerabilities have been discovered in Cisco's Internet Operating System (IOS).

Mail in Mac OS X 10.3.7, when generating a Message-ID header, generates a GUUID that includes information that identifies the Ethernet hardware being used, which allows remote attackers to link mail messages to a particular machine. The Mail application supplied with Apple's Mac OS X operating system identifies the system from which any electronic mail is sent. Apple's Mac OS X operating system contains a flaw in the handling of ICC color profiles, which may allow arbitrary code execution through a heap-based buffer overflow. An information disclosure vulnerability affects the email message ID generation of Apple Mail. This issue is due to a design error that causes the application to insecurely generate email message IDs. An attacker may leverage this issue to identify the specific computer that an email has been sent from, other attacks may also be possible

ColorSync on Mac OS X 10.3.7 and 10.3.8 allows attackers to execute arbitrary code via malformed ICC color profiles that modify the heap. The Mail application supplied with Apple's Mac OS X operating system identifies the system from which any electronic mail is sent. A remote buffer overflow vulnerability affects the International Color Consortium (ICC) color profile processing functionality of Apple ColorSync. This issue is due to a failure of the application to properly validate user-supplied data prior to copying it into static process buffers. An attacker may leverage this issue to execute arbitrary code in the context of the ColorSync utility; it is currently unknown whether the ColorSync utility runs with superuser privileges, although it is likely

Buffer overflow in the (1) -v and (2) -a switches in mRouter in iSync 1.5 in Mac OS X 10.3.7 and earlier allows local users to execute arbitrary code. iSync's 'mRouter' binary is reportedly susceptible to a local command line argument buffer overflow vulnerability. This issue is due to a failure of the application to properly bounds check user-supplied input data prior to copying it into an insufficiently sized memory buffer. The 'mRouter' binary is installed by default with setuid superuser permissions. This vulnerability allows users with local interactive access to a computer with the affected application installed to gain superuser privileges. Apple Mac OS X is a dedicated operating system developed by Apple for Mac computers. A local user could exploit this vulnerability to execute arbitrary code

Buffer overflow in the Foundation framework for Mac OS X 10.3.9 allows local users to execute arbitrary code via a long environment variable. An integer overflow in LibTIFF may allow a remote attacker to execute arbitrary code. ---------------------------------------------------------------------- Want a new IT Security job?

Stack-based buffer overflow in the VPN daemon (vpnd) for Mac OS X before 10.3.9 allows local users to execute arbitrary code via a long -i (Server_id) argument. An integer overflow in LibTIFF may allow a remote attacker to execute arbitrary code. The vulnerability presents itself when the application handles excessive string values supplied through the '-i' command line parameter. An attacker can gain superuser privileges by exploiting this issue. Due to the availability of more information, this issue is being assinged a new BID. ---------------------------------------------------------------------- Want a new IT Security job?

Cisco IOS 12.1YD, 12.2T, 12.3 and 12.3T, when configured for the IOS Telephony Service (ITS), CallManager Express (CME) or Survivable Remote Site Telephony (SRST), allows remote attackers to cause a denial of service (device reboot) via a malformed packet to the SCCP port. Cisco IOS Implemented in ITS , CME ,and SRST Is SCCP Packets are not processed properly, so if these are enabled, illegal SCCP A vulnerability exists that causes the device to restart after interpreting the packet.System disrupts service operation (DoS) It may be in a state. IOS is prone to a denial-of-service vulnerability. The issue is reported to exist in the Skinny Call Control Protocol (SCCP) handler. A remote attacker may exploit this vulnerability continuously to effectively deny network-based services to legitimate users. Cisco IOS is the underlying operating system for Cisco networking equipment

Integer signedness error in the parse_machfile function in the mach-o loader (mach_loader.c) for the Darwin Kernel as used in Mac OS X 10.3.7, and other versions before 10.3.9, allows local users to cause a denial of service (CPU consumption) via a crafted mach-o header. Apple Mac OS X is prone to a local denial of service vulnerability. This issue is exposed when the Mac OS X kernel processes an executable file, causing temporary interruption of services on the computer. Reportedly a local integer overflow vulnerability affects the Darwin Kernel. This issue is due to a failure of the affected to properly handle integer signedness. An attacker may leverage this issue to cause the affected computer to crash, denying service to legitimate users. It has been speculated that this issue may also be leverage to escalate privileges, although this is unconfirmed

Integer overflow in the searchfs system call in Mac OS X 10.3.9 and earlier allows local users to execute arbitrary code via crafted parameters. The issue occurs in the searchfs() code. The vulnerability exists due to an error in calculating size arguments derived from user-controlled integer values, which are then used in a user-land to kernel memory copy operation. The issue may be leveraged to corrupt kernel memory and ultimately execute arbitrary code with ring-0 privileges. The issue may also be exploited to trigger a denial of service condition from a kernel panic

The "at" commands on Mac OS X 10.3.7 and earlier do not properly drop privileges, which allows local users to (1) delete arbitrary files via atrm, (2) execute arbitrary programs via the -f argument to batch, or (3) read arbitrary files via the -f argument to batch, which generates a job file that is readable by the local user. The Mail application supplied with Apple's Mac OS X operating system identifies the system from which any electronic mail is sent. Apple's Mac OS X operating system contains a flaw in the handling of ICC color profiles, which may allow arbitrary code execution through a heap-based buffer overflow. These issues are due to a failure of the application to properly implement access controls on job schedule files. An attacker may leverage these issues to read and delete arbitrary files and execute applications on an affected computer with superuser privileges. Information revealed in this way may lead to further attacks. Mac OS X is a BSD-based operating system

NETGEAR FVS318 running firmware 2.4, and possibly other versions, allows remote attackers to bypass the filters using hex encoded URLs, as demonstrated using a hex encoded file extension. NetGear FVS318 is reported prone to multiple vulnerabilities. These issues result from insufficient sanitization of user-supplied data and may allow an attacker to bypass URI filters and carry out cross-site scripting attacks. The following issues were identified: It is reported that an attacker can bypass URI filters of the device. The URI filter log viewer is reported prone to a cross-site scripting vulnerability. The research report specified that FVS318 devices with firmware 2.4 are vulnerable to these issues. FVS318 and FVS318v2 are shipped with firmware 2.4, however, it is possible that FVS318v3 and other firmware versions are affected as well. This BID will be updated when more information about affected packages is available. The Netgear FVS318 is a handy little router. A filter detection bypass vulnerability exists in Netgear FVS318 with firmware version 2.4. Remote attackers can use Hex-encoded URLs, such as HEX-encoded file extensions, to bypass detection
