CVE-2014-4721

Status Candidate

Overview

The phpinfo implementation in ext/standard/info.c in PHP before 5.4.30 and 5.5.x before 5.5.14 does not ensure use of the string data type for the PHP_AUTH_PW, PHP_AUTH_TYPE, PHP_AUTH_USER, and PHP_SELF variables, which might allow context-dependent attackers to obtain sensitive information from process memory by using the integer data type with crafted values, related to a "type confusion" vulnerability, as demonstrated by reading a private SSL key in an Apache HTTP Server web-hosting environment with mod_ssl and a PHP 5.3.x mod_php.

Red Hat Security Advisory 2014-1766-01
Posted Oct 30, 2014
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2014-1766-01 - PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. A buffer overflow flaw was found in the Exif extension. A specially crafted JPEG or TIFF file could cause a PHP application using the exif_thumbnail() function to crash or, possibly, execute arbitrary code. Multiple buffer overflow flaws were found in the way PHP parsed DNS responses. A malicious DNS server or a man-in-the-middle attacker could use these flaws to crash or, possibly, execute arbitrary code with the privileges of a PHP application that uses the dns_get_record() function.

Red Hat Security Advisory 2014-1013-01 - PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. PHP's fileinfo module provides functions used to identify a particular file according to the type of data contained by the file. A denial of service flaw was found in the File Information extension rules for detecting AWK files. A remote attacker could use this flaw to cause a PHP application using fileinfo to consume an excessive amount of CPU. Multiple denial of service flaws were found in the way the File Information extension parsed certain Composite Document Format files. A remote attacker could use either of these flaws to crash a PHP application using fileinfo via a specially crafted CDF file.

Multiple denial of service flaws were found in the way the File Information extension parsed certain Composite Document Format files. A remote attacker could use either of these flaws to crash a PHP application using fileinfo via a specially crafted CDF file. Two denial of service flaws were found in the way the File Information extension handled indirect and search rules. A remote attacker could use either of these flaws to cause a PHP application using fileinfo to crash or consume an excessive amount of CPU.

Ubuntu Security Notice 2276-1 - Francisco Alonso discovered that the PHP Fileinfo component incorrectly handled certain CDF documents. A remote attacker could use this issue to cause PHP to hang or crash, resulting in a denial of service. Stefan Esser discovered that PHP incorrectly handled unserializing SPL extension objects. An attacker could use this issue to execute arbitrary code. Various other issues were also addressed.

Mandriva Linux Security Advisory 2014-130
Posted Jul 9, 2014
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2014-130 - The unserialize() function in PHP before 5.4.30 and 5.5.14 has a Type Confusion issue related to the SPL ArrayObject and SPLObjectStorage Types. It was discovered that PHP is vulnerable to a heap-based buffer overflow in the DNS TXT record parsing. A malicious server or man-in-the-middle attacker could possibly use this flaw to execute arbitrary code as the PHP interpreter if a PHP application uses dns_get_record() to perform a DNS query. A flaw was found in the way file parsed property information from Composite Document Files (CDF) files, where the mconvert() function did not correctly compute the truncated pascal string size. Multiple flaws were found in the way file parsed property information from Composite Document Files files, due to insufficient boundary checks on buffers. PHP contains a bundled copy of the file utility's libmagic library, so it was vulnerable to this issue. It has been updated to versions 5.5.14, which fix this issue and several other bugs. The phpinfo() function in PHP before 5.4.30 and 5.5.14 has a Type Confusion issue that can cause it to leak arbitrary process memory. Additionally, php-apc has been rebuilt against the updated php packages and the php-timezonedb packages has been upgraded to the 2014.5 version.
