  script_tag(name:"vuldetect", value:"Checks if a vulnerable package version is present on the target host.");

  script_tag(name:"insight", value:"The phpinfo() PHP function did not properly sanitize long strings. A
remote attacker could use this to perform cross-site scripting attacks
against sites that have publicly-available PHP scripts that call
phpinfo(). Please note that it is not recommended to publicly expose
phpinfo(). (CVE-2006-0996)

An information disclosure has been reported in the
html_entity_decode() function. A script which uses this function to
process arbitrary user-supplied input could be exploited to expose a
random part of memory, which could potentially reveal sensitive data.
(CVE-2006-1490)

The wordwrap() function did not sufficiently check the validity of the
'break' argument. An attacker who could control the string passed to
the 'break' parameter could cause a heap overflow, however, this
should not happen in practical applications. (CVE-2006-1990)

The substr_compare() function did not sufficiently check the validity
of the 'offset' argument. A script which passes untrusted user-defined
values to this parameter could be exploited to crash the PHP
interpreter. (CVE-2006-1991)

In certain situations, using unset() to delete a hash entry could
cause the deletion of the wrong element, which would leave the
specified variable defined. This could potentially cause information
disclosure in security-relevant operations. (CVE-2006-3017)

In certain situations the session module attempted to close a data
file twice, which led to memory corruption. This could potentially be
exploited to crash the PHP interpreter, though that could not be
verified. (CVE-2006-3018)

This update also fixes various bugs which allowed local scripts
to bypass open_basedir and 'safe mode' restrictions by passing special
arguments to tempnam() (CVE-2006-1494, CVE-2006-2660), copy()
(CVE-2006-1608), the curl module (CVE-2006-2563), or error_log()
(CVE-2006-3011).");
