Amazon Linux AMI : php70 (ALAS-2017-788)

High Nessus Plugin ID 96806

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

The SplObjectStorage unserialize implementation in ext/spl/spl_observer.c in PHP before 7.0.12 does not verify that a key is an object, which allows remote attackers to execute arbitrary code or cause a denial of service (uninitialized memory access) via crafted serialized data. (CVE-2016-7480)

Use-after-free vulnerability in the CURLFile implementation in ext/curl/curl_file.c in PHP 7.x before 7.0.12 allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted serialized data that is mishandled during __wakeup processing. (CVE-2016-9137)

Stack consumption vulnerability in the gdImageFillToBorder function in gd.c in the GD Graphics Library (aka libgd) before 2.2.2, as used in PHP 7.x before 7.0.13, allows remote attackers to cause a denial of service (segmentation violation) via a crafted imagefilltoborder call that triggers use of a negative color value. (CVE-2016-9933)

ext/wddx/wddx.c in PHP 7.x before 7.0.13 allows remote attackers to cause a denial of service (NULL pointer dereference) via crafted serialized data in a wddxPacket XML document, as demonstrated by a PDORow string. (CVE-2016-9934)

The php_wddx_push_element function in ext/wddx/wddx.c in PHP 7.x before 7.0.14 allows remote attackers to cause a denial of service (out-of-bounds read and memory corruption) or possibly have unspecified other impact via an empty boolean element in a wddxPacket XML document. (CVE-2016-9935)

The unserialize implementation in ext/standard/var.c in PHP 7.x before 7.0.14 allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted serialized data. This vulnerability exists because of an incomplete fix for CVE-2015-6834 . (CVE-2016-9936)

Solution

Run 'yum update php70' to update your system.
