Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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.
