Multiple unrestricted file upload vulnerabilities in the (1) twikidraw (action/twikidraw.py) and (2) anywikidraw (action/anywikidraw.py) actions in MoinMoin before 1.9.6 allow remote authenticated users with write permissions to execute arbitrary code by uploading a file with an executable extension, then accessing it via a direct request to the file in an unspecified directory, as exploited in the wild in July 2012.

Directory traversal vulnerability in the _do_attachment_move function in the AttachFile action (action/AttachFile.py) in MoinMoin 1.9.3 through 1.9.5 allows remote attackers to overwrite arbitrary files via a .. (dot dot) in a file name.

Cross-site scripting (XSS) vulnerability in bookmarks/js/bookmarks.js in ownCloud 4.0.x before 4.0.10 and 4.5.x before 4.5.5 allows remote attackers to inject arbitrary web script or HTML via the PATH_INFO to apps/bookmark/index.php.

ownCloud 4.0.x before 4.0.10 and 4.5.x before 4.5.5 does not properly restrict access to settings.php, which allows remote attackers to edit app configurations of user_webdavauth and user_ldap by editing this file.

The Context module 6.x-3.x before 6.x-3.1 and 7.x-3.x before 7.x-3.0-beta6 for Drupal does not properly restrict access to block content, which allows remote attackers to obtain sensitive information via a crafted request.

The Nodewords: D6 Meta Tags module before 6.x-1.14 for Drupal, when configured to automatically generate description meta tags from node text, does not properly filter node content when creating tags, which might allow remote attackers to obtain sensitive information by reading the (1) description, (2) dc.description or (3) og:description meta tags.

The file upload feature in Drupal 6.x before 6.27 and 7.x before 7.18 allows remote authenticated users to bypass the protection mechanism and execute arbitrary PHP code via a null byte in a file name.

Drupal 6.x before 6.27 allows remote attackers to obtain sensitive information about uploaded files via a (1) RSS feed or (2) search result.

Drupal 6.x before 6.27 and 7.x before 7.18 displays information for blocked users, which might allow remote attackers to obtain sensitive information by reading the search results.

The http_negotiate_create_context function in protocol/http/http_negotiate.c in ELinks 0.12 before 0.12pre6, when using HTTP Negotiate or GSS-Negotiate authentication, delegates user credentials through GSSAPI, which allows remote servers to authenticate as the client via the delegated credentials.

Apache CXF 2.4.x before 2.4.8, 2.5.x before 2.5.4, and 2.6.x before 2.6.1, when a Supporting Token specifies a child WS-SecurityPolicy 1.1 or 1.2 policy, does not properly ensure that an XML element is signed or encrypted, which has unspecified impact and attack vectors.

wp-php-widget.php in the WP PHP widget plugin 1.0.2 for WordPress allows remote attackers to obtain sensitive information via a direct request, which reveals the full path in an error message.

Opera before 12.12 on UNIX uses weak permissions for the profile directory, which allows local users to obtain sensitive information by reading a (1) cache file, (2) password file, or (3) configuration file, or (4) possibly gain privileges by modifying or overwriting a configuration file.

Opera before 12.12 allows remote attackers to spoof the address field via a high rate of HTTP requests.

Opera before 12.12 does not properly allocate memory for GIF images, which allows remote attackers to execute arbitrary code or cause a denial of service (memory overwrite) via a malformed image.

Opera before 12.11 allows remote attackers to determine the existence of arbitrary local files via vectors involving web script in an error page.

Heap-based buffer overflow in Opera before 12.11 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a long HTTP response.

Opera before 12.10 follows Internet shortcuts that are referenced by a (1) IMG element or (2) other inline element, which makes it easier for remote attackers to conduct phishing attacks via a crafted web site, as exploited in the wild in November 2012.

Opera before 12.10 does not properly handle incorrect size data in a WebP image, which allows remote attackers to obtain potentially sensitive information from process memory by using a crafted image as the fill pattern for a canvas.

Opera before 12.10 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a malformed SVG image.

Cross-site scripting (XSS) vulnerability in Opera before 12.10 allows remote attackers to inject arbitrary web script or HTML via crafted JavaScript code that overrides methods of unspecified native objects in documents that have different origins.

Cross-site scripting (XSS) vulnerability in Opera before 12.10 allows remote attackers to inject arbitrary web script or HTML via vectors involving an unspecified sequence of loading of documents and loading of data: URLs.

Opera before 12.10 does not properly implement the Cross-Origin Resource Sharing (CORS) specification, which allows remote attackers to bypass intended page-content restrictions via a crafted request.

The X.509 certificate-validation functionality in the https implementation in Opera before 12.10 allows remote attackers to trigger a false indication of successful revocation-status checking by causing a failure of a single checking service.

Opera before 11.67 and 12.x before 12.02 allows remote attackers to cause truncation of a dialog, and possibly trigger downloading and execution of arbitrary programs, via a crafted web site.
