Chris Evans discovered several integer overflows in xpdf, that are
also present in tetex-bin, binary files for the teTeX distribution,
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 20011202-7.3.
For the unstable distribution (sid) these problems have been fixed in
version 2.0.2-23.
We recommend that you upgrade your tetex-bin packages.
