Description

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.
