It was discovered that Ghostscript incorrectly handled certain malformed

denial of service and possibly execute arbitrary code with user privileges.
This issue only affected Ubuntu 8.04 LTS. (CVE-2009-3743)

It was discovered that Ghostscript incorrectly handled certain malformed
Type 2 fonts. If a user or automated system were tricked into opening a

denial of service and possibly execute arbitrary code with user privileges.
This issue only affected Ubuntu 8.04 LTS. (CVE-2010-4054)

Jonathan Foote discovered that Ghostscript incorrectly handled certain
