From Red Hat Security Advisory 2010:0919 :

Updated php packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4 and 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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

An input validation flaw was discovered in the PHP session serializer.
If a PHP script generated session variable names from untrusted user input, a remote attacker could use this flaw to inject an arbitrary variable into the PHP session. (CVE-2010-3065)

An information leak flaw was discovered in the PHP var_export() function implementation. If some fatal error occurred during the execution of this function (such as the exhaustion of memory or script execution time limit), part of the function's output was sent to the user as script output, possibly leading to the disclosure of sensitive information. (CVE-2010-2531)

A numeric truncation error and an input validation flaw were found in the way the PHP utf8_decode() function decoded partial multi-byte sequences for some multi-byte encodings, sending them to output without them being escaped. An attacker could use these flaws to perform a cross-site scripting attack. (CVE-2009-5016, CVE-2010-3870)

It was discovered that the PHP lcg_value() function used insufficient entropy to seed the pseudo-random number generator. A remote attacker could possibly use this flaw to predict values returned by the function, which are used to generate session identifiers by default.
This update changes the function's implementation to use more entropy during seeding. (CVE-2010-1128)

It was discovered that the PHP fnmatch() function did not restrict the length of the pattern argument. A remote attacker could use this flaw to crash the PHP interpreter where a script used fnmatch() on untrusted matching patterns. (CVE-2010-1917)

A NULL pointer dereference flaw was discovered in the PHP XML-RPC extension. A malicious XML-RPC client or server could use this flaw to crash the PHP interpreter via a specially crafted XML-RPC request.
(CVE-2010-0397)

All php users should upgrade to these updated packages, which contain backported patches to resolve these issues. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.

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

A flaw was found in the way PHP converted certain floating point values from string representation to a number. If a PHP script evaluated an attacker's input in a numeric context, the PHP interpreter could cause high CPU usage until the script execution time limit is reached. This issue only affected i386 systems.
(CVE-2010-4645)

A numeric truncation error and an input validation flaw were found in the way the PHP utf8_decode() function decoded partial multi-byte sequences for some multi-byte encodings, sending them to output without them being escaped. An attacker could use these flaws to perform a cross-site scripting attack. (CVE-2009-5016, CVE-2010-3870)

A NULL pointer dereference flaw was found in the PHP ZipArchive::getArchiveComment function. If a script used this function to inspect a specially crafted ZIP archive file, it could cause the PHP interpreter to crash. (CVE-2010-3709)

All php users should upgrade to these updated packages, which contain backported patches to resolve these issues. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.

It was discovered that an integer overflow in the XML UTF-8 decoding code could allow an attacker to bypass cross-site scripting (XSS) protections. This issue only affected Ubuntu 6.06 LTS, Ubuntu 8.04 LTS, and Ubuntu 9.10. (CVE-2009-5016)

It was discovered that the XML UTF-8 decoding code did not properly handle non-shortest form UTF-8 encoding and ill-formed subsequences in UTF-8 data, which could allow an attacker to bypass cross-site scripting (XSS) protections. (CVE-2010-3870)

It was discovered that attackers might be able to bypass open_basedir() restrictions by passing a specially crafted filename.
(CVE-2010-3436)

Maksymilian Arciemowicz discovered that a NULL pointer derefence in the ZIP archive handling code could allow an attacker to cause a denial of service through a specially crafted ZIP archive. This issue only affected Ubuntu 8.04 LTS, Ubuntu 9.10, Ubuntu 10.04 LTS, and Ubuntu 10.10. (CVE-2010-3709)

It was discovered that a stack consumption vulnerability in the filter_var() PHP function when in FILTER_VALIDATE_EMAIL mode, could allow a remote attacker to cause a denial of service. This issue only affected Ubuntu 8.04 LTS, Ubuntu 9.10, Ubuntu 10.04 LTS, and Ubuntu 10.10. (CVE-2010-3710)

It was discovered that the mb_strcut function in the Libmbfl library within PHP could allow an attacker to read arbitrary memory within the application process. This issue only affected Ubuntu 10.10.
(CVE-2010-4156)

Maksymilian Arciemowicz discovered that an integer overflow in the NumberFormatter::getSymbol function could allow an attacker to cause a denial of service. This issue only affected Ubuntu 10.04 LTS and Ubuntu 10.10. (CVE-2010-4409)

Rick Regan discovered that when handing PHP textual representations of the largest subnormal double-precision floating-point number, the zend_strtod function could go into an infinite loop on 32bit x86 processors, allowing an attacker to cause a denial of service.
(CVE-2010-4645).

According to its banner, the version of PHP installed on the remote host is older than 5.2.11.  Such versions may be affected by several security issues :

  - An unspecified error occurs in certificate validation     inside 'php_openssl_apply_verification_policy'.

  - An unspecified input validation vulnerability affects     the color index in 'imagecolortransparent()'.

  - An unspecified input validation vulnerability affects     exif processing.

  - Calling 'popen()' with an invalid mode can cause a     crash under Windows. (Bug #44683)

  - An integer overflow in 'xml_utf8_decode()' can make it     easier to bypass cross-site scripting and SQL injection     protection mechanisms using a specially crafted string     with a long UTF-8 encoding. (Bug #49687)

  - 'proc_open()' can bypass 'safe_mode_protected_env_vars'.
    (Bug #49026)

The remote host is affected by the vulnerability described in GLSA-201110-06 (PHP: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in PHP. Please review the       CVE identifiers referenced below for details.
  Impact :

    A context-dependent attacker could execute arbitrary code, obtain       sensitive information from process memory, bypass intended access       restrictions, or cause a Denial of Service in various ways.
    A remote attacker could cause a Denial of Service in various ways,       bypass spam detections, or bypass open_basedir restrictions.
  Workaround :

    There is no known workaround at this time.

Security Enhancements and Fixes in PHP 5.3.4 :

  - Fixed crash in zip extract method (possible CWE-170).
