Postscript printers open to password theft through 32-year-old flaw

HP, Lexmark and Dell printers could be hacked thanks to a 32-year-old flaw that allows an attacker to access and manipulate documents, steal passwords and shut down printers.

According to researchers at Ruhr University, around 20 models of printers are affected and these flaws are linked to common printing languages, such as PostScript and PJL.
