RHEL 3 / 4 : php (RHSA-2006:0276)
High Nessus Plugin ID 21287
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated PHP packages that fix multiple security issues are now available for Red Hat Enterprise Linux 3 and 4.
This update has been rated as having moderate security impact by the Red Hat Security Response Team.
PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Web server.
The phpinfo() PHP function did not properly sanitize long strings. An attacker could use this to perform cross-site scripting attacks against sites that have publicly-available PHP scripts that call phpinfo(). (CVE-2006-0996)
The html_entity_decode() PHP function was found to not be binary safe.
An attacker could use this flaw to disclose a certain part of the memory. In order for this issue to be exploitable the target site would need to have a PHP script which called the 'html_entity_decode()' function with untrusted input from the user and displayed the result. (CVE-2006-1490)
The error handling output was found to not properly escape HTML output in certain cases. An attacker could use this flaw to perform cross-site scripting attacks against sites where both display_errors and html_errors are enabled. (CVE-2006-0208)
An input validation error was found in the 'mb_send_mail()' function.
An attacker could use this flaw to inject arbitrary headers in a mail sent via a script calling the 'mb_send_mail()' function where the 'To' parameter can be controlled by the attacker. (CVE-2005-3883)
A buffer overflow flaw was discovered in uw-imap, the University of Washington's IMAP Server. php-imap is compiled against the static c-client libraries from imap and therefore needed to be recompiled against the fixed version. This issue only affected Red Hat Enterprise Linux 3. (CVE-2005-2933).
Users of PHP should upgrade to these updated packages, which contain backported patches that resolve these issues.
SolutionUpdate the affected packages.
