Chris Evans discovered several integer overflows in xpdf, a viewer for
PDF files, which can be exploited remotely by a specially crafted PDF
document and lead to the execution of arbitrary code.
For the stable distribution (woody) these problems have been fixed in
version 1.00-3.2.
For the unstable distribution (sid) these problems have been fixed in
version 3.00-9.
We recommend that you upgrade your xpdf package.
