Integer signedness error in the pixman_fill_sse2 function in pixman-sse2.c in Pixman, as distributed with Cairo and used in Mozilla Firefox before 20.0, Firefox ESR 17.x before 17.0.5, Thunderbird before 17.0.5, Thunderbird ESR 17.x before 17.0.5, SeaMonkey before 2.17, and other products, allows remote attackers to execute arbitrary code via crafted values that trigger attempted use of a (1) negative box boundary or (2) negative box size, leading to an out-of-bounds write operation.

MariaDB 5.5.x before 5.5.30, 5.3.x before 5.3.13, 5.2.x before 5.2.15, and 5.1.x before 5.1.68, and Oracle MySQL 5.1.69 and earlier, 5.5.31 and earlier, and 5.6.11 and earlier allows remote attackers to cause a denial of service (crash) via a crafted geometry feature that specifies a large number of points, which is not properly handled when processing the binary representation of this feature, related to a numeric calculation error.

The QSslSocket::sslErrors function in Qt before 4.6.5, 4.7.x before 4.7.6, 4.8.x before 4.8.5, when using certain versions of openSSL, uses an "incompatible structure layout" that can read memory from the wrong location, which causes Qt to report an incorrect error when certificate validation fails and might cause users to make unsafe security decisions to accept a certificate.

Mozilla Firefox before 19.0, Thunderbird before 17.0.3, and SeaMonkey before 2.16 do not prevent multiple wrapping of WebIDL objects, which allows remote attackers to bypass intended access restrictions via unspecified vectors.

Mozilla Firefox before 19.0, Firefox ESR 17.x before 17.0.3, Thunderbird before 17.0.3, Thunderbird ESR 17.x before 17.0.3, and SeaMonkey before 2.16 allow man-in-the-middle attackers to spoof the address bar by operating a proxy server that provides a 407 HTTP status code accompanied by web script, as demonstrated by a phishing attack on an HTTPS site.

Use-after-free vulnerability in the nsPrintEngine::CommonPrint function in Mozilla Firefox before 19.0, Thunderbird before 17.0.3, and SeaMonkey before 2.16 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via unspecified vectors.

The RasterImage::DrawFrameTo function in Mozilla Firefox before 19.0, Thunderbird before 17.0.3, and SeaMonkey before 2.16 allows remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read and application crash) via a crafted GIF image.

Use-after-free vulnerability in the nsOverflowContinuationTracker::Finish function in Mozilla Firefox before 19.0, Firefox ESR 17.x before 17.0.3, Thunderbird before 17.0.3, Thunderbird ESR 17.x before 17.0.3, and SeaMonkey before 2.16 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via a crafted document that uses Cascading Style Sheets (CSS) -moz-column-* properties.

Mozilla Firefox before 19.0, Firefox ESR 17.x before 17.0.3, Thunderbird before 17.0.3, Thunderbird ESR 17.x before 17.0.3, and SeaMonkey before 2.16 do not prevent JavaScript workers from reading the browser-profile directory name, which has unspecified impact and remote attack vectors.

Use-after-free vulnerability in the nsImageLoadingContent::OnStopContainer function in Mozilla Firefox before 19.0, Firefox ESR 17.x before 17.0.3, Thunderbird before 17.0.3, Thunderbird ESR 17.x before 17.0.3, and SeaMonkey before 2.16 allows remote attackers to execute arbitrary code via crafted web script.
