1.200.1. RHSA-2011:0195: Moderate security update
Updated php packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6.
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.
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.
1.200.2. RHBA-2011:0615: bug fix and enhancement update
Updated php packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. It offers developers a built-in database integration and a solution to write dynamically generated web pages.
The php packages have been upgraded to upstream version 5.3.3, which provides a number of bug fixes and adds multiple enhancements over the previous version. It also introduces one backwards-incompatible language change in that only a function named "__construct" is now treated as a constructor in a namespaced class. This change has no effect on non-namespaced classes. (
BZ#645591)
Additionally, the following bug has been fixed:
Previously, the check to prevent the "extract()" function overwriting the "$GLOBALS" variable was not working properly when using the default "EXTR_OVERWRITE" mode. The fix for this bug has been provided so that the check works as expected now. (
BZ#655118)
Users are advised to upgrade to these updated packages, which resolve these issues and add these enhancements.
