A cross-site scripting (XSS) vulnerability in phpinfo (info.c) in PHP <= 5.1.2 allows remote attackers to inject arbitrary web script or HTML via long array variables, including (1) a large number of dimensions or (2) long values, which prevents HTML tags from being removed. (CVE-2006-0996)

Directory traversal vulnerability in file.c in PHP <= 5.1.2 allows local users to bypass open_basedir restrictions and allows remote attackers to create files in arbitrary directories via the tempnam function. (CVE-2006-1494)

The copy function in file.c in PHP <= 5.1.2 allows local users to bypass safe mode and read arbitrary files via a source argument containing a compress.zlib:// URI. (CVE-2006-1608)

Updated packages have been patched to address these issues. After upgrading these packages, please run 'service httpd restart'.

Updated PHP packages that fix multiple security issues are now available for Red Hat Enterprise Linux 3 and 4.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Web server.

A directory traversal vulnerability was found in PHP. Local users could bypass open_basedir restrictions allowing remote attackers to create files in arbitrary directories via the tempnam() function.
(CVE-2006-1494)

The wordwrap() PHP function did not properly check for integer overflow in the handling of the 'break' parameter. An attacker who could control the string passed to the 'break' parameter could cause a heap overflow. (CVE-2006-1990)

A flaw was found in the zend_hash_del() PHP function. For PHP scripts that rely on the use of the unset() function, a remote attacker could force variable initialization to be bypassed. This would be a security issue particularly for installations that enable the 'register_globals' setting. 'register_globals' is disabled by default in Red Hat Enterprise Linux. (CVE-2006-3017)

Users of PHP should upgrade to these updated packages, which contain backported patches that resolve these issues.

(CVE-2006-1494)

A flaw was found in the PHP IMAP MIME header decoding function. An attacker could craft a message with an overly long header which caused PHP to crash. (CVE-2002-2214)

Users of PHP should upgrade to these updated packages, which contain backported patches that resolve these issues.

According to its banner, the version of PHP installed on the remote host is older than 4.4.3 / 5.1.4.  Such versions may be affected by several issues, including a buffer overflow, heap corruption, and a flaw by which a variable may survive a call to 'unset()'.

The phpinfo() PHP function did not properly sanitize long strings. A remote attacker could use this to perform cross-site scripting attacks against sites that have publicly-available PHP scripts that call phpinfo(). Please note that it is not recommended to publicly expose phpinfo(). (CVE-2006-0996)

An information disclosure has been reported in the html_entity_decode() function. A script which uses this function to process arbitrary user-supplied input could be exploited to expose a random part of memory, which could potentially reveal sensitive data.
(CVE-2006-1490)

The wordwrap() function did not sufficiently check the validity of the 'break' argument. An attacker who could control the string passed to the 'break' parameter could cause a heap overflow; however, this should not happen in practical applications. (CVE-2006-1990)

The substr_compare() function did not sufficiently check the validity of the 'offset' argument. A script which passes untrusted user-defined values to this parameter could be exploited to crash the PHP interpreter. (CVE-2006-1991)

In certain situations, using unset() to delete a hash entry could cause the deletion of the wrong element, which would leave the specified variable defined. This could potentially cause information disclosure in security-relevant operations. (CVE-2006-3017)

In certain situations the session module attempted to close a data file twice, which led to memory corruption. This could potentially be exploited to crash the PHP interpreter, though that could not be verified. (CVE-2006-3018)

This update also fixes various bugs which allowed local scripts to bypass open_basedir and 'safe mode' restrictions by passing special arguments to tempnam() (CVE-2006-1494, CVE-2006-2660), copy() (CVE-2006-1608), the curl module (CVE-2006-2563), or error_log() (CVE-2006-3011).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote host is running a version of PHP that is older than 5.1.4.  This version is reported vulnerable to several flaws that may allow an attacker, with the right to execute PHP scripts, the ability to execute arbitrary code.  Executed code would be run with the permissions of the web server process.
