Scientific Linux Security Update : php on SL5.x i386/x86_64

Critical Nessus Plugin ID 60445


The remote Scientific Linux host is missing one or more security updates.


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.

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 websites. 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)
