The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4339-1 advisory.
Brandon Perry discovered that OpenEXR incorrectly handled certain malformed EXR image files. If a user were tricked into opening a crafted EXR image file, a remote attacker could cause a denial of service, or possibly execute arbitrary code. This issue only applied to Ubuntu 20.04 LTS. (CVE-2017-9111, CVE-2017-9113, CVE-2017-9115)
Tan Jie discovered that OpenEXR incorrectly handled certain malformed EXR image files. If a user were tricked into opening a crafted EXR image file, a remote attacker could cause a denial of service, or possibly execute arbitrary code. This issue only applied to Ubuntu 20.04 LTS. (CVE-2018-18444)
Samuel Gro discovered that OpenEXR incorrectly handled certain malformed EXR image files. If a user were tricked into opening a crafted EXR image file, a remote attacker could cause a denial of service, or possibly execute arbitrary code.
