news 28 Posted July 22, 2008 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: php security update Advisory ID: RHSA-2008:0582-01 Product: Red Hat Application Stack Advisory URL: https://rhn.redhat.com/errata/RHSA-2008-0582.html Issue date: 2008-07-22 CVE Names: CVE-2008-2051 CVE-2007-5898 CVE-2007-5899 CVE-2007-4782 CVE-2008-2107 CVE-2008-2108 ===================================================================== 1. Summary: Updated PHP packages that fix several security issues are now available for Red Hat Application Stack v1. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Application Stack v1 for Enterprise Linux AS (v.4) - i386, x86_64 Red Hat Application Stack v1 for Enterprise Linux ES (v.4) - i386, x86_64 3. Description: PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Web server. It was discovered that the PHP escapeshellcmd() function did not properly escape multi-byte characters which are not valid in the locale used by the script. This could allow an attacker to bypass quoting restrictions imposed by escapeshellcmd() and execute arbitrary commands if the PHP script was using certain locales. Scripts using the default UTF-8 locale are not affected by this issue. (CVE-2008-2051) PHP functions htmlentities() and htmlspecialchars() did not properly recognize partial multi-byte sequences. Certain sequences of bytes could be passed through these functions without being correctly HTML-escaped. Depending on the browser being used, an attacker could use this flaw to conduct cross-site scripting attacks. (CVE-2007-5898) A PHP script which used the transparent session ID configuration option, or which used the output_add_rewrite_var() function, could leak session identifiers to external web sites. If a page included an HTML form with an ACTION attribute referencing a non-local URL, the user's session ID would be included in the form data passed to that URL. (CVE-2007-5899) It was discovered that PHP fnmatch() function did not restrict the length of the string argument. An attacker could use this flaw to crash the PHP interpreter where a script used fnmatch() on untrusted input data. (CVE-2007-4782) It was discovered that PHP did not properly seed its pseudo-random number generator used by functions such as rand() and mt_rand(), possibly allowing an attacker to easily predict the generated pseudo-random values. (CVE-2008-2107, CVE-2008-2108) Users of PHP should upgrade to these updated packages, which contain backported patches to correct these issues. 4.
