An issue was discovered in PHP 5.x and 7.x, when the configuration uses apache2handler/mod_php or php-fpm with OpCache enabled. With 5.x after 5.6.28 or 7.x after 7.0.13, the issue is resolved in a non-default configuration with the opcache.validate_permission=1 setting. The vulnerability details are as follows. In PHP SAPIs where PHP interpreters share a common parent process, Zend OpCache creates a shared memory object owned by the common parent during initialization. Child PHP processes inherit the SHM descriptor, using it to cache and retrieve compiled script bytecode ("opcode" in PHP jargon). Cache keys vary depending on configuration, but filename is a central key component, and compiled opcode can generally be run if a script's filename is known or can be guessed. Many common shared-hosting configurations change EUID in child processes to enforce privilege separation among hosted users (for example using mod_ruid2 for the Apache HTTP Server, or php-fpm user settings). In these scenarios, the default Zend OpCache behavior defeats script file permissions by sharing a single SHM cache among all child PHP processes. PHP scripts often contain sensitive information: Think of CMS configurations where reading or running another user's script usually means gaining privileges to the CMS database.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3382-1 advisory.

    It was discovered that the PHP opcache created keys for files it cached based on their filepath. A local     attacker could possibly use this issue in a shared hosting environment to obtain sensitive information.
    This issue only affected Ubuntu 14.04 LTS. (CVE-2015-8994)

    It was discovered that the PHP URL parser incorrectly handled certain URI components. A remote attacker     could possibly use this issue to bypass hostname-specific URL checks. This issue only affected Ubuntu     14.04 LTS. (CVE-2016-10397)

    It was discovered that PHP incorrectly handled certain boolean parameters when unserializing data. A     remote attacker could possibly use this issue to cause PHP to crash, resulting in a denial of service.
    This issue only affected Ubuntu 14.04 LTS. (CVE-2017-11143)

    Sebastian Li, Wei Lei, Xie Xiaofei, and Liu Yang discovered that PHP incorrectly handled the OpenSSL     sealing function. A remote attacker could possibly use this issue to cause PHP to crash, resulting in a     denial of service. (CVE-2017-11144)

    Wei Lei and Liu Yang discovered that the PHP date extension incorrectly handled memory. A remote attacker     could possibly use this issue to disclose sensitive information from the server. (CVE-2017-11145)

    It was discovered that PHP incorrectly handled certain PHAR archives. A remote attacker could use this     issue to cause PHP to crash or disclose sensitive information. This issue only affected Ubuntu 14.04 LTS.
    (CVE-2017-11147)

    It was discovered that PHP incorrectly handled locale length. A remote attacker could possibly use this     issue to cause PHP to crash, resulting in a denial of service. (CVE-2017-11362)

    Wei Lei and Liu Yang discovered that PHP incorrectly handled parsing ini files. An attacker could possibly     use this issue to cause PHP to crash, resulting in a denial of service. (CVE-2017-11628)

    It was discovered that PHP mbstring incorrectly handled certain regular expressions. A remote attacker     could use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute     arbitrary code. (CVE-2017-9224, CVE-2017-9226, CVE-2017-9227, CVE-2017-9228, CVE-2017-9229)
