Google Chrome before 4.0.249.78 on Windows does not perform the expected encoding, escaping, and quoting for the URL in the --app argument in a desktop shortcut, which allows user-assisted remote attackers to execute arbitrary programs or obtain sensitive information by tricking a user into creating a crafted shortcut.

WebKit before r51295, as used in Google Chrome before 4.0.249.78, presents a directory-listing page in response to an XMLHttpRequest for a file:/// URL that corresponds to a directory, which allows attackers to obtain sensitive information or possibly have unspecified other impact via a crafted local HTML document.

Mozilla Firefox 3.5.x before 3.5.11 and 3.6.x before 3.6.7, Thunderbird 3.0.x before 3.0.6 and 3.1.x before 3.1.1, and SeaMonkey before 2.0.6 permit cross-origin loading of CSS stylesheets even when the stylesheet download has an incorrect MIME type and the stylesheet document is malformed, which allows remote attackers to obtain sensitive information via a crafted document.

WebKit before r52784, as used in Google Chrome before 4.0.249.78 and Apple Safari before 4.0.5, permits cross-origin loading of CSS stylesheets even when the stylesheet download has an incorrect MIME type and the stylesheet document is malformed, which allows remote attackers to obtain sensitive information via a crafted document.

WebKit, as used in Google Chrome before 4.0.249.78 and Apple Safari, allows remote attackers to bypass intended restrictions on popup windows via crafted use of a mouse click event.

Integer overflow in the CrossCallParamsEx::CreateFromBuffer function in sandbox/src/crosscall_server.cc in Google Chrome before 4.0.249.89 allows attackers to leverage renderer access to cause a denial of service (heap memory corruption) or possibly have unspecified other impact via a malformed message, related to deserializing of sandbox messages.

Mozilla Firefox, possibly before 3.6, allows remote attackers to discover a redirect's target URL, for the session of a specific user of a web site, by placing the site's URL in the HREF attribute of a stylesheet LINK element, and then reading the document.styleSheets[0].href property value, related to an IFRAME element.

WebKit before r53525, as used in Google Chrome before 4.0.249.89, allows remote attackers to execute arbitrary code in the Chrome sandbox via a malformed RUBY element, as demonstrated by a <ruby>><table><rt> sequence.

Multiple integer signedness errors in factory.cc in Google V8 before r3560, as used in Google Chrome before 4.0.249.89, allow remote attackers to execute arbitrary code in the Chrome sandbox via crafted use of JavaScript arrays.

Multiple integer overflows in factory.cc in Google V8 before r3560, as used in Google Chrome before 4.0.249.89, allow remote attackers to execute arbitrary code in the Chrome sandbox via crafted use of JavaScript arrays.

Google Chrome before 4.0.249.89, when a SOCKS 5 proxy server is configured, sends DNS queries directly, which allows remote DNS servers to obtain potentially sensitive information about the identity of a client user via request logging, as demonstrated by a proxy server that was configured for the purpose of anonymity.

Google Chrome before 4.0.249.89 attempts to make direct connections to web sites when all configured proxy servers are unavailable, which allows remote HTTP servers to obtain potentially sensitive information about the identity of a client user via standard HTTP logging, as demonstrated by a proxy server that was configured for the purpose of anonymity.

The htcpHandleTstRequest function in htcp.c in Squid 2.x before 2.6.STABLE24 and 2.7 before 2.7.STABLE8, and htcp.cc in 3.0 before 3.0.STABLE24, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via crafted packets to the HTCP port.

Cross-site request forgery (CSRF) vulnerability in WebCalendar 1.2.0 allows remote attackers to hijack the authentication of administrators for requests that change the administrative password via unknown vectors. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

Multiple cross-site request forgery (CSRF) vulnerabilities in WebCalendar 1.2.0, and other versions before 1.2.5, allow remote attackers to hijack the authentication of administrators for requests that (1) delete an event or (2) ban an IP address from posting via unknown vectors. NOTE: some of these details are obtained from third party information.

Multiple cross-site scripting (XSS) vulnerabilities in WebCalendar 1.2.0, and other versions before 1.2.5, allow remote attackers to inject arbitrary web script or HTML via the (1) tab parameter to users.php and the PATH_INFO to (2) day.php, (3) month.php, and (4) week.php. NOTE: some of these details are obtained from third party information.
