Heap-based buffer overflow in the error-handling mechanism for the IIS ISAPI handler in Macromedia JRun 4.0 and earlier allows remote attackers to execute arbitrary via an HTTP GET request with a long .jsp file name.

Heap-based buffer overflow in the error-handling mechanism for the IIS ISAPI handler in Macromedia ColdFusion 6.0 allows remote attackers to execute arbitrary via an HTTP GET request with a long .cfm file name.

Heap-based buffer overflow in Netscape and Mozilla allows remote attackers to execute arbitrary code via a jar: URL that references a malformed .jar file, which overflows a buffer during decompression.

Multiple buffer overflows in LISa on KDE 2.x for 2.1 and later, and KDE 3.x before 3.0.4, allow (1) local and possibly remote attackers to execute arbitrary code via the "lisa" daemon, and (2) remote attackers to execute arbitrary code via a certain "lan://" URL.

The Microsoft Java implementation, as used in Internet Explorer, allows remote attackers to cause a denial of service (crash) and possibly conduct other unauthorized activities via applet tags in HTML that bypass Java class restrictions (such as private constructors) by providing the class name in the code parameter, aka "Incomplete Java Object Instantiation Vulnerability."

The Microsoft Java implementation, as used in Internet Explorer, can provide HTML object references to applets via Javascript, which allows remote attackers to cause a denial of service (crash due to illegal memory accesses) and possibly conduct other unauthorized activities via an applet that uses those references to access proprietary Microsoft methods.

The Microsoft Java implementation, as used in Internet Explorer, provides a public load0() method for the CabCracker class (com.ms.vm.loader.CabCracker), which allows remote attackers to bypass the security checks that are performed by the load() method.

The Microsoft Java virtual machine (VM) build 5.0.3805 and earlier, as used in Internet Explorer, allows remote attackers to extend the Standard Security Manager (SSM) class (com.ms.security.StandardSecurityManager) and bypass intended StandardSecurityManager restrictions by modifying the (1) deniedDefinitionPackages or (2) deniedAccessPackages settings, causing a denial of service by adding Java applets to the list of applets that are prevented from running.

The Microsoft Java implementation, as used in Internet Explorer, allows remote attackers to read restricted process memory, cause a denial of service (crash), and possibly execute arbitrary code via the getNativeServices function, which creates an instance of the com.ms.awt.peer.INativeServices (INativeServices) class, whose methods do not verify the memory addresses that are passed as parameters.

The Microsoft Java implementation, as used in Internet Explorer, allows remote attackers to steal cookies and execute script in a different security context via a URL that contains a colon in the domain portion, which is not properly parsed and loads an applet from a malicious site within the security context of the site that is being visited by the user.

Unknown vulnerability in the telnet KIO subsystem (telnet.protocol) of KDE 2.x 2.1 and later allows local and remote attackers to execute arbitrary code via a certain URL.

Unknown vulnerability in the rlogin KIO subsystem (rlogin.protocol) of KDE 2.x 2.1 and later, and KDE 3.x 3.0.4 and earlier, allows local and remote attackers to execute arbitrary code via a certain URL.

Buffer overflow in named in BIND 4 versions 4.9.10 and earlier, and 8 versions 8.3.3 and earlier, allows remote attackers to execute arbitrary code via a certain DNS server response containing SIG resource records (RR).

Heap-based buffer overflow in the Remote Data Services (RDS) component of Microsoft Data Access Components (MDAC) 2.1 through 2.6, and Internet Explorer 5.01 through 6.0, allows remote attackers to execute code via a malformed HTTP request to the Data Stub.

Buffer overflows in the DNS stub resolver library in ISC BIND 4.9.2 through 4.9.10, and other derived libraries such as BSD libc and GNU glibc, allow remote attackers to execute arbitrary code via DNS server responses that trigger the overflow in the (1) getnetbyname, or (2) getnetbyaddr functions, aka "LIBRESOLV: buffer overrun" and a different vulnerability than CVE-2002-0684.

runlpr in the LPRng package allows the local lp user to gain root privileges via certain command line arguments.

Multiple buffer overflows in conf.c for Masqmail 0.1.x before 0.1.17, and 0.2.x before 0.2.15, allow local users to gain privileges via certain entries in the configuration file (-C option).

Buffer overflow in LISa allows local users to gain access to a raw socket via a long LOGNAME environment variable for the resLISa daemon.

SSH Secure Shell for Servers and SSH Secure Shell for Workstations 2.0.13 through 3.2.1, when running without a PTY, does not call setsid to remove the child process from the process group of the parent process, which allows attackers to gain certain privileges.

importInfo in the Admin Server for iPlanet WebServer 4.x, up to SP11, allows the web administrator to execute arbitrary commands via shell metacharacters in the dir parameter, and possibly allows remote attackers to exploit this vulnerability via a separate XSS issue (CVE-2002-1315).

Cross-site scripting (XSS) vulnerability in the Admin Server for iPlanet WebServer 4.x, up to SP11, allows remote attackers to execute web script or HTML as the iPlanet administrator by injecting the desired script into error logs, and possibly escalating privileges by using the XSS vulnerability in conjunction with another issue (CVE-2002-1316).

The Microsoft Java implementation, as used in Internet Explorer, allows remote attackers to read and modify the contents of the Clipboard via an applet that accesses the (1) ClipBoardGetText and (2) ClipBoardSetText methods of the INativeServices class.

Mailtool for OpenWindows 3.6, 3.6.1, and 3.6.2 allows remote attackers to cause a denial of service (mailtool segmentation violation and crash) via a malformed mail attachment.

The Microsoft Java implementation, as used in Internet Explorer, allows remote attackers to read arbitrary local files and network shares via an applet tag with a codebase set to a "file://%00" (null character) URL.

The Microsoft Java implementation, as used in Internet Explorer, allows remote attackers to determine the current directory of the Internet Explorer process via the getAbsolutePath() method in a File() call.

Stack-based buffer overflow in the Microsoft Java implementation, as used in Internet Explorer, allows remote attackers to cause a denial of service via a long class name through (1) Class.forName or (2) ClassLoader.loadClass.

Buffer overflow in Novell iManager (eMFrame) before 1.5 allows remote attackers to cause a denial of service via an authentication request with a long Distinguished Name (DN) attribute.

BIND 8.x through 8.3.3 allows remote attackers to cause a denial of service (crash) via SIG RR elements with invalid expiry times, which are removed from the internal BIND database and later cause a null dereference.

BIND 8.3.x through 8.3.3 allows remote attackers to cause a denial of service (termination due to assertion failure) via a request for a subdomain that does not exist, with an OPT resource record with a large UDP payload size.

Qualcomm Eudora 5.1.1, 5.2, and possibly other versions stores email attachments in a predictable location, which allows remote attackers to read arbitrary files via a link that loads an attachment with malicious script into a frame, which then executes the script in the local browser context.

Netscape Communicator 4.x allows attackers to use a link to steal a user's preferences, including potentially sensitive information such as URL history, e-mail address, and possibly the e-mail password, by redefining the user_pref() function and accessing the prefs.js file, which is stored in a directory with a predictable name.

Courier sqwebmail before 0.40.0 does not quickly drop privileges after startup in certain cases, which could allow local users to read arbitrary files.

The wizard in KGPG 0.6 through 0.8.2 does not properly provide the passphrase to gpg when creating new keys, which causes secret keys to be created with an empty passphrase and allows local attackers to steal the keys if they can be read.

An incomplete fix for a cross-site scripting (XSS) vulnerability in SquirrelMail 1.2.8 calls the strip_tags function on the PHP_SELF value but does not save the result back to that variable, leaving it open to cross-site scripting attacks.

nullmailer 1.00RC5 and earlier allows local users to cause a denial of service via an email to a local user that does not exist, which generates an error that causes nullmailer to stop sending mail to all users.
