The remote Scientific Linux host is missing one or more security
A heap-based buffer overflow flaw was found in PHP's mbstring
extension. A remote attacker able to pass arbitrary input to a PHP
script using mbstring conversion functions could cause the PHP
interpreter to crash or, possibly, execute arbitrary code.
A flaw was found in the handling of the 'mbstring.func_overload'
configuration setting. A value set for one virtual host, or in a
user's .htaccess file, was incorrectly applied to other virtual hosts
on the same server, causing the handling of multibyte character
strings to not work correctly. (CVE-2009-0754)
A buffer overflow flaw was found in PHP's imageloadfont function. If a
PHP script allowed a remote attacker to load a carefully crafted font
file, it could cause the PHP interpreter to crash or, possibly,
execute arbitrary code. (CVE-2008-3658)
A flaw was found in the way PHP handled certain file extensions when
running in FastCGI mode. If the PHP interpreter was being executed via
FastCGI, a remote attacker could create a request which would cause
the PHP interpreter to crash. (CVE-2008-3660)
A cross-site scripting flaw was found in a way PHP reported errors for
invalid cookies. If the PHP interpreter had 'display_errors' enabled,
a remote attacker able to set a specially crafted cookie on a victim's
system could possibly inject arbitrary HTML into an error message
generated by PHP. (CVE-2008-5814) - SL5 Only
A memory disclosure flaw was found in the PHP gd extension's
imagerotate function. A remote attacker able to pass arbitrary values
as the 'background color' argument of the function could, possibly,
view portions of the PHP interpreter's memory. (CVE-2008-5498)
The httpd web server must be restarted for the changes to take effect.
