The remote host is missing an update to tetex-bin announced via advisory DSA 937-1. infamous41md and Chris Evans discovered several heap based buffer overflows in xpdf, the Portable Document Format (PDF) suite, which is also present in tetex-bin, the binary files of teTeX, and which can lead to a denial of service by crashing the application or possibly to the execution of arbitrary code. For the old stable distribution (woody) these problems have been fixed in version 1.0.7+20011202-7.7.

For the stable distribution (sarge) these problems have been fixed in version 2.0.2-30sarge4. For the unstable distribution (sid) these problems have been fixed in version 0.4.3-2 of poppler against which tetex-bin links.
