Xpdf is an X Window System based viewer for Portable Document Format (PDF)
files.
An uninitialized pointer use flaw was discovered in Xpdf. An attacker could
create a malicious PDF file that, when opened, would cause Xpdf to crash
or, potentially, execute arbitrary code. (CVE-2010-3702)
An array index error was found in the way Xpdf parsed PostScript Type 1
fonts embedded in PDF documents. An attacker could create a malicious PDF
file that, when opened, would cause Xpdf to crash or, potentially, execute
arbitrary code. (CVE-2010-3704)
Users are advised to upgrade to this updated package, which contains
backported patches to correct these issues.
poppler, CUPS, gpdf und KPDF are also affected
EDIT2
libpoppler seems to be the bad guy so far
It's the development environment and test bed for a very nice, very stable distro called Red Hat Enterprise Linux. Fedora is not something I'd want to run on a regular basis, but that's just me.
