"Drew Yao discovered several flaws in the way OpenEXR handled certain
malformed EXR image files. If a user were tricked into opening a
crafted EXR image file, an attacker could cause a denial of service
via application crash, or possibly execute arbitrary code with the
privileges of the user invoking the program. (CVE-2009-1720,
CVE-2009-1721)

It was discovered that OpenEXR did not properly handle certain
malformed EXR image files. If a user were tricked into opening a
crafted EXR image file, an attacker could cause a denial of service
via application crash, or possibly execute arbitrary code with the
privileges of the user invoking the program. This issue only affected
Ubuntu 8.04 LTS. (CVE-2009-1722).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
