PHP < 5.3.9 Multiple Vulnerabilities

High Log Correlation Engine Plugin ID 801116

Synopsis

The remote web server uses a version of PHP that is affected by multiple vulnerabilities.

Description

Versions of PHP earlier than 5.3.9 are potentially affected by multiple vulnerabilities :

- It is possible to create a denial of service condition by sending multiple, specially crafted requests containing parameter values that cause hash collisions when computing the hash values for storage in a hash table. (CVE-2011-4885)

- An integer overflow exists in the exif_process_IFD_TAG function in exif.c that can allow a remote attacker to read arbitrary memory locations or cause a denial of service condition. This vulnerability only affects PHP 5.4.0beta2 on 32-bit platforms. (CVE-2011-4566)

- Calls to libxslt are not restricted via xsltSetSecurityPrefs(), which could allow an attacker to create or overwrite file, resulting in arbitrary code execution. (CVE-2012-0057)

- An error exists in the function 'tidy_diagnose' that can allow an attacker to cause the application to dereference a null pointer. This causes the application to crash. (CVE-2012-0781)

- The 'PDORow' implementation contains an error that can cause application crashes when interacting with the session feature. C(VE-2012-0788)

- An error exists in the timezone handling such that repeated calls to the function 'strtotime' can allow a denial of service attack via memory consuption. (CVE-2012-0789)

Solution

Upgrade to PHP version 5.3.9 or later.
