Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2006-2563)

The vulnerability allows a local user to gain access to sensitive information.

The cURL library (libcurl) in PHP 4.4.2 and 5.1.4 allows attackers to bypass safe mode and read files via a file:// request containing null characters.


2) Heap-based buffer overflow (CVE-ID: CVE-2006-1990)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing data within the wordwrap function in string.c in PHP 4.4.2 and 5.1.2 might allow context-dependent attackers to execute arbitrary code via certain long arguments that cause a small buffer to be allocated, which triggers a heap-based buffer overflow in a memcpy function call. A remote attacker can pass a specially crafted file to the affected application, trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


3) Resource management error (CVE-ID: CVE-2006-1549)

The vulnerability allows a local user to perform service disruption.

PHP 4.4.2 and 5.1.2 allows local users to cause a crash (segmentation fault) by defining and executing a recursive function. NOTE: it has been reported by a reliable third party that some later versions are also affected. Upgrade to PHP 5.1.3-RC3


4) Cross-site scripting (CVE-ID: CVE-2006-0996)

Vulnerability allows a remote attacker to perform Cross-site scripting attacks.

An input validation error exists in phpinfo (info.c) in PHP 5.1.2 and 4.4.2. A remote authenticated attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in victim's browser in security context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
