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). + </p> + <p> + 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) + </p> + <p> + 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. + </p> + <p> + 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. + </p> + <p> + 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). + </p> + <p> + 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. + </p> + </description> + <impact type="high"> + <p> + 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. + </p> + </impact> + <workaround> + <p> + There is no known workaround at this time. + </p> + </workaround> + <resolution> + <p> + All PHP users should upgrade to the latest version: + </p> + <code> + # emerge --sync + # emerge --ask --oneshot --verbose ">=dev-lang/php-5.2.4_p20070914-r2"</code> + </resolution> + <references> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1883">CVE-2007-1883</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1887">CVE-2007-1887</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1900">CVE-2007-1900</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2756">CVE-2007-2756</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2872">CVE-2007-2872</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3007">CVE-2007-3007</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3378">CVE-2007-3378</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3806">CVE-2007-3806</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3996">CVE-2007-3996</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3997">CVE-2007-3997</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3998">CVE-2007-3998</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4652">CVE-2007-4652</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4657">CVE-2007-4657</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4658">CVE-2007-4658</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4659">CVE-2007-4659</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4660">CVE-2007-4660</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4661">CVE-2007-4661</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4662">CVE-2007-4662</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4663">CVE-2007-4663</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4670">CVE-2007-4670</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4727">CVE-2007-4727</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4782">CVE-2007-4782</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4783">CVE-2007-4783</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4784">CVE-2007-4784</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4825">CVE-2007-4825</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4840">CVE-2007-4840</uri> + <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4887">CVE-2007-4887</uri> + <uri link="http://www.gentoo.org/security/en/glsa/glsa-200705-19.xml">GLSA 200705-19</uri> + </references> + <metadata tag="requester" timestamp="Sun, 19 Aug 2007 18:58:47 +0000"> + jaervosz + </metadata> + <metadata tag="bugReady" timestamp="Sun, 19 Aug 2007 18:58:59 +0000"> + jaervosz + </metadata> + <metadata tag="submitter" timestamp="Thu, 27 Sep 2007 00:18:38 +0000"> + rbu + </metadata> +</glsa> |
