Discussion

Ximian Evolution MIME image/* Content-Type Data Inclusion Vulnerability

Ximian Evolution does not properly validate MIME image/* Content-Type fields. If an email message contains an image/* Content-Type, any type of data can be embedded where the image information is expected. This can be used to embed HTML tags that will be rendered by GTKHtml, bypass policies, or invoke bonobo components to handle external content types.

Exploit / POC

The following example will cause heap corruption:
