CVE Id(s)      : CVE-2008-3863 CVE-2008-4306

Several vulnerabilities have been discovered in Enscript, a converter
from ASCII text to Postscript, HTML or RTF. The Common Vulnerabilities
and Exposures project identifies the following problems:

CVE-2008-3863

   Ulf Harnhammer discovered that a buffer overflow may lead to
   the execution of arbitrary code.

CVE-2008-4306

   Kees Cook and Tomas Hoger discovered that several buffer
   overflows may lead to the execution of arbitrary code.

For the stable distribution (etch), these problems have been fixed in
