dvips
and xdvi
both have the ability to automatically generate TeX font files from metafont sources when displaying/converting a DVI document. This is done by invoking the MakeTeXPK
utility with the font name, plus a few other options.Unfortunately, the code invoking
MakeTeXPK
did not properly sanitize the font name. By embedding shell meta characters in font names included in a DVI document, an attacker was able to execute arbitrary commands under the account of the user viewing or processing the document. This includes the printer daemon if you use lpdfilter
to transparently process document formats other than postscript, because lpdfilter
will try to convert DVI files to PostScript(tm) using dvips
