    A security issue affects these releases of Ubuntu and its
    derivatives:

    Summary

    USN-3911-1 introduced a regression in file.

    Software Description

    * file - Tool to determine file types

    Details

    USN-3911-1 fixed vulnerabilities in file. One of the backported
    security fixes introduced a regression that caused the interpreter
    string to be truncated. This update fixes the problem.

    We apologize for the inconvenience.

    Original advisory details:

    It was discovered that file incorrectly handled certain malformed
    ELF files. An attacker could use this issue to cause a denial of
    service, or possibly execute arbitrary code.
