It was discovered that Ghostscript incorrectly handled certain malformed
files. If a user or automated system were tricked into opening a crafted
Postscript or PDF file, an attacker could cause a denial of service or
execute arbitrary code with privileges of the user invoking the program.
This issue only affected Ubuntu 8.04 LTS and Ubuntu 9.04. (CVE-2009-4897)

Dan Rosenberg discovered that Ghostscript incorrectly handled certain
recursive Postscript files. If a user or automated system were tricked into
opening a crafted Postscript file, an attacker could cause a denial of
service or execute arbitrary code with privileges of the user invoking the
program. (CVE-2010-1628)

Rodrigo Rubira Branco and Dan Rosenberg discovered that Ghostscript
incorrectly handled certain malformed Postscript files. If a user or
automated system were tricked into opening a crafted Postscript file, an
attacker could cause a denial of service or execute arbitrary code with
