According to its banner, the version of PHP 5.5.x installed on the remote host is prior to 5.5.18. It is, therefore, affected by the following vulnerabilities :

  • A buffer overflow error exists in the function ‘mkgmtime’ that can allow application crashes or arbitrary code execution. (CVE-2014-3668)

  • An integer overflow error exists in the function ‘unserialize’ that can allow denial of service attacks.
    Note that this only affects 32-bit instances.
    (CVE-2014-3669)

  • A heap corruption error exists in the function ‘exif_thumbnail’ that can allow application crashes or arbitrary code execution. (CVE-2014-3670)

  • An input-validation error exists in the cURL extension’s file ‘ext/curl/interface.c’ and NULL option handling that can allow information disclosure. (Bug #68089)

Note that Nessus has not attempted to exploit these issues but has instead relied only on the application’s self-reported version number.
