The dl function in PHP 5.2.4 and earlier allows context-dependent attackers to cause a denial of service (application crash) via a long string in the library parameter. NOTE: there are limited usage scenarios under which this would be a vulnerability.

The remote host is running a version of Mac OS X 10.5 or 10.4 that does not have the security update 2008-002 applied. 

This update contains several security fixes for a number of programs.

PHP project reports :

Security Enhancements and Fixes in PHP 5.2.5 :

- Fixed dl() to only accept filenames. Reported by Laurent Gaffie.

- Fixed dl() to limit argument size to MAXPATHLEN (CVE-2007-4887).
Reported by Laurent Gaffie.

- Fixed htmlentities/htmlspecialchars not to accept partial multibyte sequences. Reported by Rasmus Lerdorf

- Fixed possible triggering of buffer overflows inside glibc implementations of the fnmatch(), setlocale() and glob() functions.
Reported by Laurent Gaffie.

- Fixed 'mail.force_extra_parameters' php.ini directive not to be modifiable in .htaccess due to the security implications. Reported by SecurityReason.

- Fixed bug #42869 (automatic session id insertion adds sessions id to non-local forms).

- Fixed bug #41561 (Values set with php_admin_* in httpd.conf can be overwritten with ini_set()).

According to its banner, the version of PHP installed on the remote host is older than 5.2.5.  Such versions may be affected by various issues, including but not limited to several buffer overflows.

New PHP5 packages are available for Slackware 10.1, 10.2, 11.0, 12.0, and -current to fix security and other bugs. Note that PHP5 was not officially supported in Slackware 10.1 or 10.2 (being in the /testing directory), and was not the default version of PHP for Slackware 11.0 (being in the /extra directory), but updates are being provided anyway.

The remote host is affected by the vulnerability described in GLSA-200710-02 (PHP: Multiple vulnerabilities)

    Several vulnerabilities were found in PHP. Mattias Bengtsson and Philip     Olausson reported integer overflows in the gdImageCreate() and     gdImageCreateTrueColor() functions of the GD library which can cause     heap-based buffer overflows (CVE-2007-3996). Gerhard Wagner discovered     an integer overflow in the chunk_split() function that can lead to a     heap-based buffer overflow (CVE-2007-2872). Its incomplete fix caused     incorrect buffer size calculation due to precision loss, also resulting     in a possible heap-based buffer overflow (CVE-2007-4661 and     CVE-2007-4660). A buffer overflow in the sqlite_decode_binary() of the     SQLite extension found by Stefan Esser that was addressed in PHP 5.2.1     was not fixed correctly (CVE-2007-1887).
    Stefan Esser discovered an error in the zend_alter_ini_entry() function     handling a memory_limit violation (CVE-2007-4659). Stefan Esser also     discovered a flaw when handling interruptions with userspace error     handlers that can be exploited to read arbitrary heap memory     (CVE-2007-1883). Disclosure of sensitive memory can also be triggered     due to insufficient boundary checks in the strspn() and strcspn()     functions, an issue discovered by Mattias Bengtsson and Philip Olausson     (CVE-2007-4657)     Stefan Esser reported incorrect validation in the FILTER_VALIDATE_EMAIL     filter of the Filter extension allowing arbitrary email header     injection (CVE-2007-1900). NOTE: This CVE was referenced, but not fixed     in GLSA 200705-19.
    Stanislav Malyshev found an error with unknown impact in the     money_format() function when processing '%i' and '%n' tokens     (CVE-2007-4658). zatanzlatan reported a buffer overflow in the     php_openssl_make_REQ() function with unknown impact when providing a     manipulated SSL configuration file (CVE-2007-4662). Possible memory     corruption when trying to read EXIF data in exif_read_data() and     exif_thumbnail() occurred with unknown impact.
    Several vulnerabilities that allow bypassing of open_basedir and other     restrictions were reported, including the glob() function     (CVE-2007-4663), the session_save_path(), ini_set(), and error_log()     functions which can allow local command execution (CVE-2007-3378),     involving the readfile() function (CVE-2007-3007), via the Session     extension (CVE-2007-4652), via the MySQL extension (CVE-2007-3997) and     in the dl() function which allows loading extensions outside of the     specified directory (CVE-2007-4825).
    Multiple Denial of Service vulnerabilities were discovered, including a     long 'library' parameter in the dl() function (CVE-2007-4887), in     several iconv and xmlrpc functions (CVE-2007-4840 and CVE-2007-4783),     in the setlocale() function (CVE-2007-4784), in the glob() and     fnmatch() function (CVE-2007-4782 and CVE-2007-3806), a floating point     exception in the wordwrap() function (CVE-2007-3998), a stack     exhaustion via deeply nested arrays (CVE-2007-4670), an infinite loop     caused by a specially crafted PNG image in the png_read_info() function     of libpng (CVE-2007-2756) and several issues related to array     conversion.
  Impact :

    Remote attackers might be able to exploit these issues in PHP     applications making use of the affected functions, potentially     resulting in the execution of arbitrary code, Denial of Service,     execution of scripted contents in the context of the affected site,     security bypass or information leak.
  Workaround :

    There is no known workaround at this time.
