ALAS-2016-728


Amazon Linux AMI Security Advisory: ALAS-2016-728
Advisory Release Date: 2016-08-17 13:30 Pacific
Severity: Medium

Issue Overview:

A stack consumption vulnerability in GD in PHP allows remote attackers to cause a denial of service via a crafted imagefilltoborder call. (CVE-2015-8874 )

An integer overflow, leading to a heap-based buffer overflow was found in the imagecreatefromgd2() function of PHP's gd extension. A remote attacker could use this flaw to crash a PHP application or execute arbitrary code with the privileges of the user running that PHP application, using gd via a specially crafted GD2 image. (CVE-2016-5766 )

An integer overflow, leading to a heap-based buffer overflow was found in the gdImagePaletteToTrueColor() function of PHP's gd extension. A remote attacker could use this flaw to crash a PHP application or execute arbitrary code with the privileges of the user running that PHP application, using gd via a specially crafted image buffer. (CVE-2016-5767 )

A double free flaw was found in the mb_ereg_replace_callback() function of php which is used to perform regex search. This flaw could possibly cause a PHP application to crash. (CVE-2016-5768 )

The mcrypt_generic() and mdecrypt_generic() functions are prone to integer overflows, resulting in a heap-based overflow. A remote attacker could use this flaw to crash a PHP application or execute arbitrary code with the privileges of the user running that PHP application. (CVE-2016-5769 )

A type confusion issue was found in the SPLFileObject fread() function. A remote attacker able to submit a specially crafted input to a PHP application, which uses this function, could use this flaw to execute arbitrary code with the privileges of the user running that PHP application. (CVE-2016-5770 )

A use-after-free vulnerability that can occur when calling unserialize() on untrusted input was discovered. A remote attacker could use this flaw to crash a PHP application or execute arbitrary code with the privileges of the user running that PHP application if the application unserializes untrusted input. (CVE-2016-5771 , CVE-2016-5773 )

A double free can occur in wddx_deserialize() when trying to deserialize malicious XML input from user's request. This flaw could possibly cause a PHP application to crash. (CVE-2016-5772 )

It was discovered that PHP did not properly protect against the HTTP_PROXY variable name clash. A remote attacker could possibly use this flaw to redirect HTTP requests performed by a PHP script to an attacker-controlled proxy via a malicious HTTP request. (CVE-2016-5385 )

(Updated on 2016-08-17: CVE-2016-5385 was fixed in this release but was not previously part of this errata)
