Bugzilla Bug 203287

poplix has discovered a vulnerability in PDFlib, which can be exploited by
malicious people to cause a DoS (Denial of Service) or potentially compromise
an application using the library.

The vulnerability is caused due to a boundary error within the
"pdc_fsearch_fopen()" function. This can be exploited to cause a stack-based
buffer overflow via e.g. a call to "PDF_load_image()" with an overly long
filename parameter.

NOTE: Other functions are also reportedly affected by similar boundary errors.

The vulnerability is confirmed in version 7.0.2 for Linux on IA-32. Other
versions may also be affected.

Reproducible: Always

cc'ing maintainers. According to the advisory, upstream already is working on a
patch.

Since the PDFlib version we are shipping, is actually the "Lite" variant, we
should check if that is also affected.

Confirmed for 7.02

could someone please add CVE-2007-6561 to the topic?
i dont have the needed permissions to do that

Thankies, done. :)

Upstream expects a release in roughly four weeks.

New upstream release fixes this. php herd, please bump:
http://www.pdflib.com/binaries/PDFlib/702/PDFlib-Lite-7.0.2p8.tar.gz

Yeah, I'd love to have this bumped, alas I just wasted two hours of my time
with their broken configure scripts.

pdflib-7.0.2_p8 InCVS...

Any attempts to cleanup up the ebuild failed since:
- ruby support is hard-disabled as the configure magic is heavily broken, and
requires a patch even to disable it
- emake install still doesn't work, installs to ${D}/${D}
- even einstall requires manual hacks to not install stuff to broken locations
- no, I don't know what makes it spit out the following warning and I frankly
don't care

bzip2: Can't open input file
/var/tmp/portage/media-libs/pdflib-7.0.2_p8/image/usr/share/doc/pdflib-7.0.2_p8//pdflib:
No such file or directory.
</snip>

archies, please test and stabilize; tested and working here with USE="cxx -doc
-java perl python -tcl" on x86 and amd64, everything else is untested and I
hope I won't have to touch the ebuild for quite some time.

@mips - either rekeyword this now or lose pdflib altogether, all the remaining
versions will go away ASAP.
