PHP 5.6.x < 5.6.30 Multiple DoS

critical Web App Scanning Plugin ID 98821

Synopsis

PHP 5.6.x < 5.6.30 Multiple DoS

Description

According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.30. It is, therefore, affected by the following vulnerabilities :

- A floating pointer exception flaw exists in the exif_convert_any_to_int() function in exif.c that is triggered when handling TIFF and JPEG image tags. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition. (CVE-2016-10158)

- An integer overflow condition exists in the phar_parse_pharfile() function in phar.c due to improper validation when handling phar archives. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition. (CVE-2016-10159)

- An off-by-one overflow condition exists in the phar_parse_pharfile() function in phar.c due to improper parsing of phar archives. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition. (CVE-2016-10160)

- An out-of-bounds read error exists in the finish_nested_data() function in var_unserializer.c due to improper validation of unserialized data. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition or the disclosure of memory contents. (CVE-2016-10161)

- An out-of-bounds read error exists in the phar_parse_pharfile() function in phar.c due to improper parsing of phar archives. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition.

- A denial of service vulnerability exists in the bundled GD Graphics Library (LibGD) in the gdImageCreateFromGd2Ctx() function in gd_gd2.c due to improper validation of images. An unauthenticated, remote attacker can exploit this, via a specially crafted image, to crash the process.

Note that the scanner has not attempted to exploit this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to PHP version 5.6.30 or later.
