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 was updated to version 5.3.3 to fix serveral security issues.

(CVE-2010-0397, CVE-2010-1860, CVE-2010-1862, CVE-2010-1864, CVE-2010-1866, CVE-2010-1914, CVE-2010-1915, CVE-2010-1917, CVE-2010-2093, CVE-2010-2094, CVE-2010-2097, CVE-2010-2100, CVE-2010-2101, CVE-2010-2190, CVE-2010-2191, CVE-2010-2225, CVE-2010-2531, CVE-2010-2950, CVE-2010-3062, CVE-2010-3063, CVE-2010-3064, CVE-2010-3065)

According to its banner, the version of PHP 5.3 installed on the remote host is older than 5.3.3.  Such versions may be affected by several security issues :

  - An error exists when processing invalid XML-RPC     requests that can lead to a NULL pointer     dereference. (bug #51288) (CVE-2010-0397)

  - An error exists in the function 'shm_put_var' that     is related to resource destruction.

  - An error exists in the function 'fnmatch' that can lead     to stack exhaustion. (CVE-2010-1917)

  - A memory corruption error exists related to call-time     pass by reference and callbacks.

  - The dechunking filter is vulnerable to buffer overflow.

  - An error exists in the sqlite extension that could     allow arbitrary memory access.

  - An error exists in the 'phar' extension related to     string format validation.

  - The functions 'mysqlnd_list_fields' and     'mysqlnd_change_user' are vulnerable to buffer overflow.

  - The Mysqlnd extension is vulnerable to buffer overflow     attack when handling error packets.

  - The following functions are not properly protected     against function interruptions :

    addcslashes, chunk_split, html_entity_decode,     iconv_mime_decode, iconv_substr, iconv_mime_encode,     htmlentities, htmlspecialchars, str_getcsv,     http_build_query, strpbrk, strtr, str_pad,     str_word_count, wordwrap, strtok, setcookie,     strip_tags, trim, ltrim, rtrim, substr_replace,     parse_str, pack, unpack, uasort, preg_match, strrchr     (CVE-2010-1860, CVE-2010-1862, CVE-2010-1864,     CVE-2010-2097, CVE-2010-2100, CVE-2010-2101,     CVE-2010-2190, CVE-2010-2191, CVE-2010-2484)

  - The following opcodes are not properly protected     against function interruptions :

    ZEND_CONCAT, ZEND_ASSIGN_CONCAT, ZEND_FETCH_RW, XOR     (CVE-2010-2191)

  - The default session serializer contains an error     that can be exploited when assigning session     variables having user defined names. Arbitrary     serialized values can be injected into sessions by     including the PS_UNDEF_MARKER, '!', character in     variable names.

  - A use-after-free error exists in the function     'spl_object_storage_attach'. (CVE-2010-2225)

  - An information disclosure vulnerability exists in the     function 'var_export' when handling certain error     conditions. (CVE-2010-2531)

This is a maintenance and security update that upgrades php to 5.2.14 for CS4/MES5/2008.0/2009.0/2009.1.

Security Enhancements and Fixes in PHP 5.2.14 :

  - Rewrote var_export() to use smart_str rather than output     buffering, prevents data disclosure if a fatal error     occurs (CVE-2010-2531).

  - Fixed a possible interruption array leak in     strrchr().(CVE-2010-2484)

  - Fixed a possible interruption array leak in strchr(),     strstr(), substr(), chunk_split(), strtok(),     addcslashes(), str_repeat(), trim().

  - Fixed a possible memory corruption in substr_replace().

The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2010-502:05 advisory.

    PHP is an HTML-embedded scripting language. PHP attempts to make it easy for developers to write     dynamically generated webpages. PHP also offers built-in database integration for several commercial and     non-commercial database management systems, so writing a database-enabled webpage with PHP is fairly     simple. The most common use of PHP coding is probably as a replacement for CGI scripts. The mod_php module     enables the Apache Web server to understand and process the embedded PHP language in Web pages.
    Security issues fixed with this release:
    CVE-2009-5016     Integer overflow in the xml_utf8_decode function in ext/xml/xml.c in PHP before 5.2.11 makes it easier for     remote attackers to bypass cross-site scripting (XSS) and SQL injection protection mechanisms via a     crafted string that uses overlong UTF-8 encoding, a different vulnerability than CVE-2010-3870.
    CVE-2010-0397     The xmlrpc extension in PHP 5.3.1 does not properly handle a missing methodName element in the first     argument to the xmlrpc_decode_request function, which allows context-dependent attackers to cause a denial     of service (NULL pointer dereference and application crash) and possibly have unspecified other impact via     a crafted argument.
    CVE-2010-1128     The Linear Congruential Generator (LCG) in PHP before 5.2.13 does not provide the expected entropy, which     makes it easier for context-dependent attackers to guess values that were intended to be unpredictable, as     demonstrated by session cookies generated by using the uniqid function.
    CVE-2010-1917     Stack consumption vulnerability in PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 allows context-dependent     attackers to cause a denial of service (PHP crash) via a crafted first argument to the fnmatch function,     as demonstrated using a long string.
    CVE-2010-2531     The var_export function in PHP 5.2 before 5.2.14 and 5.3 before 5.3.3 flushes the output buffer to the     user when certain fatal errors occur, even if display_errors is off, which allows remote attackers to     obtain sensitive information by causing the application to exceed limits for memory, execution time, or     recursion.
    CVE-2010-3065     The default session serializer in PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 does not properly handle     the PS_UNDEF_MARKER marker, which allows context-dependent attackers to modify arbitrary session variables     via a crafted session variable name.
    CVE-2010-3870     The utf8_decode function in PHP before 5.3.4 does not properly handle non-shortest form UTF-8 encoding and     ill-formed subsequences in UTF-8 data, which makes it easier for remote attackers to bypass cross-site     scripting (XSS) and SQL injection protection mechanisms via a crafted string.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Several vulnerabilities were discovered in PHP, which could lead to denial of service or potentially the execution of arbitrary code.

  - CVE-2010-2531     An information leak was found in the var_export()     function.

  - CVE-2011-0421     The Zip module could crash.

  - CVE-2011-0708     An integer overflow was discovered in the Exif module.

  - CVE-2011-1466     An integer overflow was discovered in the Calendar     module.

  - CVE-2011-1471     The Zip module was prone to denial of service through     malformed archives.

  - CVE-2011-2202     Path names in form based file uploads (RFC 1867) were     incorrectly validated.

This update also fixes two bugs, which are not treated as security issues, but fixed nonetheless, see README.Debian.security for details on the scope of security support for PHP (CVE-2011-0420, CVE-2011-1153 ).
