Details

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)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 9.04
Ubuntu 8.10
Ubuntu 8.04

In general, a standard system upgrade is sufficient to effect the
necessary changes.
