An attacker could entice a user to visit a malicious web application that sets an "sql_query" cookie and is hosted on the same domain as phpMyAdmin, and thereby conduct SQL injection attacks with the privileges of the user authenticating in phpMyAdmin afterwards.

Red Hat bug #436024: "The Utils::runScripts function in src/utils.cpp in vdccm 0.92 through 0.10.0 in SynCE (SynCE-dccm) allows remote attackers to execute arbitrary commands via shell metacharacters in a certain string to TCP port 5679."

From the CVE notice:

The internationalization (i18n) framework in Django 0.91, 0.95, 0.95.1, and 0.96, and as used in other products such as PyLucid, when the USE_I18N option and the i18n component are enabled, allows remote attackers to cause a denial of service (memory consumption) via many HTTP requests with large Accept-Language headers.

From the National Vulnerability Database:

Buffer overflow in emacs allows attackers to have an unknown impact, as demonstrated via a vector involving the command line.

Firebird does not properly handle certain types of XDR requests, resulting in an integer overflow (CVE-2008-0387). Furthermore, it is vulnerable to a buffer overflow when processing usernames (CVE-2008-0467).

A remote attacker could send specially crafted XDR requests or an overly long username to the vulnerable server, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application.

Michal Zalewski reported that it was possible to bypass the same-origin checks and read from cached (wyciwyg) documents It is possible to access wyciwyg:// documents without proper same domain policy checks through the use of HTTP 302 redirects. This enables the attacker to steal sensitive data displayed on dynamically generated pages; perform cache poisoning; and execute own code or display own content with URL bar and SSL certificate data of the attacked page (URL spoofing++). (CVE-2007-3656)

Internet Explorer calls registered URL protocols without escaping quotes and may be used to pass unexpected and potentially dangerous data to the application that registers that URL Protocol. (CVE-2007-3670)

Ronald van den Heetkamp reported that a filename URL containing %00 (encoded null) can cause Firefox to interpret the file extension differently than the underlying Windows operating system potentially leading to unsafe actions such as running a program. This is only accessible locally. (CVE-2007-3285)

An attacker can use an element outside of a document to call an event handler allowing content to run arbitrary code with chrome privileges. (CVE-2007-3737)

Ronen Zilberman and Michal Zalewski both reported that it was possible to exploit a timing issue to inject content into about:blank frames in a page. When opening a window from a script, it is possible to spoof the content of the newly opened window's frames within a short time frame, while the window is loading. (CVE-2007-3089)

Mozilla contributor moz_bug_r_a4 demonstrated that the methods addEventListener and setTimeout could be used to inject script into another site in violation of the browser's same-origin policy. This could be used to access or modify private or valuable information from that other site. (CVE-2007-3736)

As part of the Firefox 2.0.0.5 update releases Mozilla developers fixed many bugs to improve the stability of the product. Some of these crashes that showed evidence of memory corruption under certain circumstances and we presume that with enough effort at least some of these could be exploited to run arbitrary code. Note: Thunderbird shares the browser engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail. Without further investigation we cannot rule out the possibility that for some of these an attacker might be able to prepare memory for exploitation through some means other than JavaScript, such as large images. (CVE-2007-3734, CVE-2007-3735)

NOTE: this is similar to CVE-2007-5232. (CVE-2007-5273)

Sun Java Runtime Environment (JRE) in JDK and JRE 6 Update 2 and earlier, JDK and JRE 5.0 Update 12 and earlier, SDK and JRE 1.4.2_15 and earlier, and SDK and JRE 1.3.1_20 and earlier, when Firefox or Opera is used, allows remote attackers to violate the security model for JavaScript outbound connections via a multi-pin DNS rebinding attack dependent on the LiveConnect API, in which JavaScript download relies on DNS resolution by the browser, but JavaScript socket operations rely on separate DNS resolution by a Java Virtual Machine (JVM), a different issue than CVE-2007-5273. NOTE: this is similar to CVE-2007-5232. (CVE-2007-5274)

Previous versions of the Linux kernel package contain a vulnerability in the ptrace system call which allows local users to cause a Denial of Service.
