Description
The ps encoders, responsible for writing PostScript files, fails to sanitize the input before writing it into the PostScript header. An attacker can provide a malicious file and inject arbitrary PostScript code. When the resulting file is processed by a printer or a viewer (like Ghostscript), the injected code is interpreted and executed.
The html encoder does not properly escape strings that are written to in the html document. An attacker can provide a malicious file and injection arbitrary html code.
