The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a…

Mozilla Firefox before 35.0 and SeaMonkey before 2.32 do not properly initialize memory for BMP images, which allows remote attackers to obtain sensitive information from process memory via a crafted web page that triggers the rendering of malformed BMP data within a CANVAS element.
