Buffer overflow in the portmapper service (PMAP.NLM) in Novell NetWare 6 SP3 and ZenWorks for Desktops 3.2 SP2 through 4.0.1 allows remote attackers to cause a denial of service and possibly execute arbitrary code via unknown attack vectors. Novell has reported that the PMAP.NLM component of NetWare/ZenWorks is prone to a buffer overrun vulnerability

Buffer overflow in iwconfig allows local users to execute arbitrary code via a long HOME environment variable. A problem has been identified in the iwconfig program when handling strings on the commandline. Because of this, a local attacker may be able to gain elevated privileges. iwconfig has a buffer overflow vulnerability

Origo ASR-8100 ADSL Router 3.21 has an administration service running on port 254 that does not require a password, which allows remote attackers to cause a denial of service by restoring the factory defaults. A problem has been identified in some Origo ADSL routers. Due to insufficient access control, it may be possible for a remote user to gain unauthorized administrative access to routers, potentially resulting in a denial of service. Origo ADSL includes a telnet-based configuration interface on the WAN interface, listening to port 254, and does not set any password authentication

CiscoWorks Common Management Foundation (CMF) 2.1 and earlier allows the guest user to gain administrative privileges via a certain POST request to com.cisco.nm.cmf.servlet.CsAuthServlet, possibly involving the "cmd" parameter with a modifyUser value and a modified "priviledges" parameter. Vulnerabilities exist in CiscoWorks Common Management Foundation (CMF) 2.1 and earlier versions

CiscoWorks Common Management Foundation (CMF) 2.1 and earlier allows the guest user to obtain restricted information and possibly gain administrative privileges by changing the "guest" user to the Admin user on the Modify or delete users pages. Vulnerabilities exist in CiscoWorks Common Management Foundation (CMF) 2.1 and earlier versions

SQL injection vulnerability in variables.php in Goldlink 3.0 allows remote attackers to execute arbitrary SQL commands via the (1) vadmin_login or (2) vadmin_pass cookie in a request to goldlink.php. GoldLink is prone to SQL injection attacks. This is due to insufficient validation of values supplied via cookies. As a result, it may be possible to manipulate SQL queries, potentially resulting in information disclosure, bulletin board compromise or other consequences

PHP-Nuke 7.0 allows remote attackers to obtain the installation path via certain characters such as (1) ", (2) ', or (3) > in the search field, which reveals the path in an error message. PHP-Nuke is prone to a path disclosure vulnerability. Path information will be displayed in error output when invalid input is supplied in search fields. This issue may be related to a number of previously reported vulnerabilities in PHP-Nuke. PHP-Nuke is a popular website creation and management tool, it can use many database software as backend, such as MySQL, PostgreSQL, mSQL, Interbase, Sybase, etc. PHP-Nuke does not properly handle search requests submitted by users. Attackers can use this information to carry out further attacks on the system

Buffer overflow in the system log viewer of Linksys BEFSX41 1.44.3 allows remote attackers to cause a denial of service via an HTTP request with a long Log_Page_Num variable. Linksys BEFSX41 is a broadband router that includes a web-based management interface.  Linksys BEFSX41 lacks sufficient filtering when processing user-submitted input. Remote attackers can use this vulnerability to conduct denial-of-service attacks on routers.  Linksys BEFSX41 general default address (http://192.168.1.1) contains a WEB-based management interface, which can be accessed using "get" mode. Due to lack of sufficient filtering of the "Log_Page_Num" parameter, when a long string is sent to the system log Viewer "Log_Page_Num" parameter can cause router to crash. Linksys BEFSX41 EtherFast Routers are prone to a denial of service. This issue is exposed via the log viewer in the web administrative interface. By submitting an invalid value for the "Log_Page_Num" parameter, it is possible to trigger this condition, causing the router to be unresponsive. While exploitation does require a logged in administrative user to submit a request to the log viewer with malformed parameters, it is possible that the admin could be tricked into visiting a specially crafted URI that contains the IP address of the router and malformed URI parameters

The Conexant Access Runner DSL is a broadband router. There is a problem with the authentication mechanism of the Conexant Access Runner DSL Router Console, which can be exploited by remote attackers to access device changes. When connecting to the router console port, an attacker entering any key will return a \"please try again\" message, and then simply enter the Enter key to access the system maintenance menu with administrator privileges. However, this vulnerability is reproduced on some devices, and this issue does not exist on some devices. The authentication mechanism used by the Conexant AccessRunner DSL Console can be bypassed. This could allow a remote user to access the device's configuration settings. There is currently no known reason for why some devices are vulnerable while others are not. This record will be updated if and when further details become available

The Cisco LEAP challenge/response authentication mechanism uses passwords in a way that is susceptible to dictionary attacks, which makes it easier for remote attackers to gain privileges via brute force password guessing attacks. Successful attackers will be able to gain unauthorized access to affected networks

The SMC2404WBR is a wireless CABLE/DSL broadband router. SMC routers cannot properly handle randomly sent UDP packet port scans. Remote attackers can exploit this vulnerability to perform denial of service attacks on routers. Sending random UDP packets to ports 0-65000 on the router can cause the router to hang and stop responding to normal services. A denial of service has been reported in the SMC SMC2404WBR BarricadeT Turbo 11/22 Mbps Wireless Cable/DSL Broadband Router. This condition was reportedly reproduced using one of the exploits for BID 8525. The SMC7004VWBR router is also affected by this vulnerability

The arplookup function in FreeBSD 5.1 and earlier, Mac OS X before 10.2.8, and possibly other BSD-based systems, allows remote attackers on a local subnet to cause a denial of service (resource starvation and panic) via a flood of spoofed ARP requests. A vulnerability has been discovered in the BSD kernel. The problem occurs in the storage of ARP cache entries when handling ARP requests. As a result of this issue, an attacker capable of transmitted a large volume of spoofed ARP requests to a target system may be capable of triggering a system panic. This would effectively deny services to other legitimate users until the system is manually rebooted. The issue is reported to exist in FreeBSD, IRIX and MacOS X. Other systems, which use a BSD-derived kernel, may also be prone to the issue. Address Resolution Protocol (ARP) is a protocol for mapping IP addresses to MAC addresses. Through forged ARP requests, remote attackers can carry out denial of service attacks on the system, causing the system to crash. Under some conditions, an attacker can perform a flood attack through forged ARP requests, which can cause resource exhaustion. Since the arplookup() function does not delete unnecessary ARP buffer entries, it will consume a large amount of resources and crash the system, resulting in denial of service. The attacker must hang or crash the target machine in the local network segment, and the network using ARP proxy can also cause the machine in the network segment to be attacked

The prescan function in Sendmail 8.12.9 allows remote attackers to execute arbitrary code via buffer overflow attacks, as demonstrated using the parseaddr function in parseaddr.c. sendmail A buffer overflow vulnerability was discovered in the email address parsing process. This vulnerability CERT Advisory CA-2003-07, CA-2003-12 This is a new vulnerability that differs from the vulnerability reported in. As for the vulnerability, there is a possibility that a third party may obtain administrator authority from a remote location. This problem, sendmail Occurs by receiving a message with a maliciously configured email address. For this reason, LAN Is running on a host sendmail Even other MTA (Mail Transfer Agent) If you receive a malicious message relayed from, you may be affected by the vulnerability.Service operation interruption (denial-of-service, DoS) An attacker or a remote third party may gain administrative privileges. This issue is different than the vulnerability described in BID 7230. Sendmail is one of the most popular mail transfer agents (MTAs) on the Internet. The local exploitation method on Linux can use recipient.c and sendtolist() to overwrite the pointer with the data submitted by the user. When calling the free() function, the command may be redirected, and the attacker can construct a malicious email message and submit it to Sendmail for analysis. Execute arbitrary commands on the system with Sendmail process privileges. There may also be other exploit methods, and it is also possible to exploit this vulnerability remotely

A "potential buffer overflow in ruleset parsing" for Sendmail 8.12.9, when using the nonstandard rulesets (1) recipient (2), final, or (3) mailer-specific envelope recipients, has unknown consequences. This vulnerability could allow a remote attacker to execute arbitrary code or cause a denial of service on a vulnerable system.This vulnerability does not affect the default configuration. Note that Sendmail under a default configuration is not vulnerable to this issue

A "buffer management error" in buffer_append_space of buffer.c for OpenSSH before 3.7 may allow remote attackers to execute arbitrary code by causing an incorrect amount of memory to be freed and corrupting the heap, a different vulnerability than CVE-2003-0695. While the full impact of these vulnerabilities are unclear, they may lead to memory corruption and a denial-of-service situation. ------------ This vulnerability information is a summary of multiple vulnerabilities released at the same time. Please note that the contents of vulnerability information other than the title are included. ------------ OpenSSH Project More distributed OpenSSH 3.7 (Portable Edition OpenSSH 3.7p1) Previously, there were deficiencies in buffer management. If a remote attacker receives a packet of a deliberate length that frees other nearby areas when releasing the buffer, the heap area can be destroyed. As a result, remote attackers who exploit this issue sshd Can be put into a denial of service, and arbitrary code execution has been suggested. The routine in which the problem exists is OpenSSH Others that are using similar routines since being used since the initial release of SSH The implementation of may also be affected. SSH Secure Shell/Ciso IOS Has been reported by the vendor to be unaffected by this issue. Also, F-Secure SSH about, 1.3.14 (for Unix) Previously affected, 2.x Since then, the vendor has reported that it will not be affected. Initially this problem (CAN-2003-0693) Is buffer.c Inside buffer_append_space() Discovered in the function, OpenSSH 3.7p1 It was solved with. However, since a similar problem was discovered in other places after that, this problem was solved. OpenSSH 3.7.1p1 Has been released. (CAN-2003-0695) In addition, memory management issues that are different from the above issues (CAN-2003-0682) Has also been reported, OpenSSH 3.7.1p2 It can be solved by updating to. still, Red Hat Linux About the vendor 2003 Year 9 Moon 17 Advisory published by date (RHSA-2003:279-17) Indicated in RPM Updates to the package, Turboinux About the vendor 2003 Year 9 Moon 24 Advisory published on date (TLSA-2003-53) All of these issues are due to updates to the packages indicated in (CAN-2003-0682/CAN-2003-0693/CAN-2003-0695) Can be eliminated.Please refer to the “Overview” for the impact of this vulnerability. The issue may cause a denial of service. This condition can reportedly be triggered by an overly large packet. There are also unconfirmed rumors of an exploit for this vulnerability circulating in the wild. OpenSSH has revised their advisory, pointing out a similar issue in the 'channels.c' source file and an additional issue in 'buffer.c'. Solar Designer has also reportedly pointed out additional instances of the problem that may also present vulnerabilities

Multiple buffer overflows in WS_FTP 3 and 4 allow remote authenticated users to cause a denial of service and possibly execute arbitrary code via long (1) APPE (append) or (2) STAT (status) arguments. It has been reported that a vulnerability exists in the processing of a "STAT" command on WS_FTP Servers versions 4.x and prior. Exploitation of this vulnerability may lead to an authenticated user executing arbitrary code with the elevated privileges of the server process. Ipswitch WS_FTP Server is reported to be prone to buffer overruns when handling data supplied to the APPE and STAT FTP commands. Progress Software Ipswitch WS_FTP Server is a set of FTP server software developed by Progress Software Company in the United States. It provides functions such as file transfer control and transfer encryption
