Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) NULL pointer dereference (CVE-ID: CVE-2012-0781)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via crafted input to an application that attempts to perform Tidy::diagnose operations on invalid objects, a different vulnerability than CVE-2011-4153.


2) NULL pointer dereference (CVE-ID: CVE-2011-4153)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via crafted input to an application that performs strndup operations on untrusted string data, as demonstrated by the define function in zend_builtin_functions.c, and unspecified functions in ext/soap/php_sdl.c, ext/standard/syslog.c, ext/standard/browscap.c, ext/oci8/oci8.c, ext/com_dotnet/com_typeinfo.c, and main/php_open_temporary_file.c.


3) Code Injection (CVE-ID: CVE-2011-3379)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The is_a function in PHP 5.3.7 and 5.3.8 triggers a call to the __autoload function, which makes it easier for remote attackers to execute arbitrary code by providing a crafted URL and leveraging potentially unsafe behavior in certain PEAR packages and custom autoloaders.
