pdftex and xpdf (and its security bugs): What about a libxpdf?
by frank＠kuesterei.ch 24 Jan '06

24 Jan '06

Dear pdftex developers, during the last months security support for software containing xpdf code was a nightmare - not only that there were many security issues discovered, moreover everybody used a different patch, it was unclear to what extent older versions were affected, and so forth. This was also a problem for us, the teTeX maintainer in Debian, which currently has three versions of pdftex with three different versions of the xpdf code. What would you think about creating a shared library, "libxpdf", and using that for pdftex, either linked dynamically (for Linux/Unix distributions) or statically (for TeX-live and friends)? There is already such a library, libpoppler, a fork of the xpdf code (http://poppler.freedesktop.org/) However, I do not know whether the xpdf author, Derek B. Noonburg, is generally unwilling to create a shared library, or whether people simply didn't ask him. Personally I would prefer to have as little a number of versions of the same code, and thus to get a shared library from xpdf proper. If you agree, I would be oblidged if one of you would contact Derek Noonburg (derekn(a)foolabs.com) and ask him. He seems to be a little unresponsive at times, and has not answered a similar question from the maintainer of the xpdf package in Debian for a couple of weeks now. Maybe we can convince him that this is a good idea if he is approached from different sides. Alternatively, if he is unwilling to make this change, do you think using libpoppler would be feasible? Many thanks in advance, Frank Küster -- Frank Küster Inst. f. Biochemie der Univ. Zürich Debian Developer

[ pdftex-Bugs-302 ] -jobname doesn't overcome texput

Bugs item #302, was opened at 2005-03-01 13:06 You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=302&group_id=106 Category: None Group: v1.21a Status: Open Resolution: None Priority: 5 Submitted By: John Denker (jsd) Assigned to: Nobody (None) Summary: -jobname doesn't overcome texput Initial Comment: Hi -- Suppose I want to pipe commands into pdflatex: echo '\typeout{---\jobname---}' | \ pdflatex --jobname foo You might expect that to type out ---foo--- but instead it types out ---texput--- I observe that --jobname works just fine for any filename I can think of, just not when the filename is absent entirely. I can offer two workarounds: 1) It's not documented, but nevertheless possible to \def\jobname{foo}. 2) Of course it's possible to stuff the commands into tmp.tex and then pdflatex --jobname foo tmp.tex Because these workarounds exist, I would rate this as a very low-priority bug. But it had me surprised and confused for a while. Given the overall high quality of the product, I thought I'd bring it to your attention. ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=302&group_id=106

Making a do...while loop from the while loop does allocation via t1_getline() in time, see the patch. Maybe that's enough for now to close the bug. It seems that the function t1_read_enc() is anyway called only via get_enc() when pdfmovechars > 0, so both functions serve only this special case, and are normally not in use. I have done not any check whether \pdfmovechars general functionality is ok, and one might as well thow out this primitive, and the unneeded functions. Let's add a note "deprecated" in the manual...

In my case, the symptom was that pdflatex run without error, but a wrong /Length1 parameter was inserted in the PDF output file, which evidently caused Acrobat Reader's error message (no problem, however, with xpdf or with the "dvips -Ppdf" routine). I think I solved the problem by changing the order and rules how shared libraries are found and handled on my Sun Sparc Solaris 2.9 system, and/or I may have re-installed some programs and libraries (ncurses, gettext, libiconv).

Further digging I find that when I run the linker command on the older solaris 9 machine it produces a faulty executable BUT if I run "g++ -v" to see what the real linking command is and cut and paste it so as to run it instead the executable produces a pdf viewable with acroread.

In my case, the symptom was that pdflatex run without error, but a wrong /Length1 parameter was inserted in the PDF output file, which evidently caused Acrobat Reader's error message (no problem, however, with xpdf or with the "dvips -Ppdf" routine). I think I solved the problem by changing the order and rules how shared libraries are found and handled on my Sun Sparc Solaris 2.9 system, and/or I may have re-installed some programs and libraries (ncurses, gettext, libiconv). I am sorry not being more specific on So, we have at least three people with this problem: Stan Swiercz, Maksym Polyakov, Adrian Lanz. I think that this is some king of compiler bug or something like that...

[ pdftex-Bugs-315 ] pdflatex on solaris font problems with acroread

Bugs item #315, was opened at 2005-03-21 16:53 You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=315&group_id=106 Category: Fonts Group: v1.21a >Status: Open Resolution: Fixed Priority: 5 Submitted By: Stan Swiercz (swiercz) Assigned to: Martin Schröder (oneiros) Summary: pdflatex on solaris font problems with acroread Initial Comment: I have compiled pdflatex 1.2.1a that comes with teTeX 3.0 on both linux and solaris. The linux version works properly but the solaris one does not. The last font included in the pdf output produces the error: Unable to extract the embedded font 'KTGBVU+CMR8'. Some characters may not display or print correctly. when viewed with acroread (version 5 or 6, windows, linux and solaris versions). Note that no error is seen when viewed with ghostscript and xpdf. The above error comes from the file: ------------------------ \documentclass{article} \newcommand{\ip}[2]{(#1, #2)} \begin{document} This is an example input file. Footnotes \footnote{This is an example of a footnote.} pose no problem. \LaTeX\ is good at typesetting mathematical formulas like $ x-3y + z = 7 $ or $ a_{1} > x^{2n} + y^{2n} > x' $ or $ \ip{A}{B} = \sum_{i} a_{i} b_{i} $. The spaces you type in a formula are ignored. Remember that a letter like $x$ % $ ... $ and $ ... $ are equivalent is a formula when it denotes a mathematical symbol, and it should be typed as one. \end{document} ----------------------- The sigma is produced correctly. If however I comment out the footnote, the sigma in the summation is no longer viewable and the error message is Unable to extract the embedded font 'ATSTIO+CMEX10'. Some characters may not display or print correctly. I attach a pdf files produced on solaris. Is this a know problem with a patch available? If you need further information please do not hesitate to contact me.

It's unclear, as it seems that this could happen only if the font is not being included. Anyway: Could some Solaris freak try out the attached tiny patch to writet1.c?
