Array index error in smal_decode_segment function in LibRaw before 0.17.1 allows context-dependent attackers to cause memory errors and possibly execute arbitrary code via vectors related to indexes.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Array index error in smal_decode_segment function in LibRaw before 0.17.1 allows context-dependent     attackers to cause memory errors and possibly execute arbitrary code via vectors related to indexes.
    (CVE-2015-8366)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3492-1 advisory.

    It was discovered that LibRaw incorrectly handled photo files. If a user or automated system were tricked     into processing a specially crafted photo file, a remote attacker could cause applications linked against     LibRaw to crash, resulting in a denial of service, or possibly execute arbitrary code

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
