The Bonjour functionality in mDNSResponder, iChat 3.1.6, and InstantMessage framework 428 in Apple Mac OS X 10.4.8 does not check for duplicate entries when adding newly discovered available contacts, which allows remote attackers to cause a denial of service (disrupted communication) via a flood of duplicate _presence._tcp mDNS queries.

Multiple ActiveX controls in Microsoft Windows 2000, XP, 2003, and Vista allows remote attackers to cause a denial of service (Internet Explorer crash) by accessing the bgColor, fgColor, linkColor, alinkColor, vlinkColor, or defaultCharset properties in the (1) giffile, (2) htmlfile, (3) jpegfile, (4) mhtmlfile, (5) ODCfile, (6) pjpegfile, (7) pngfile, (8) xbmfile, (9) xmlfile, (10) xslfile, or (11) wdfile objects in (a) mshtml.dll; or the (12) TriEditDocument.TriEditDocument or (13) TriEditDocument.TriEditDocument.1 objects in (b) triedit.dll, which cause a NULL pointer dereference.

Multiple cross-site scripting (XSS) vulnerabilities in Free LAN In(tra|ter)net Portal (FLIP) before 1.0-RC2 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors in (1) inc.page.php and (2) inc.text.php.

Cross-site scripting (XSS) vulnerability in the mailform feature in CMSimple 2.7 fix1 allows remote attackers to inject arbitrary web script or HTML via the sender parameter. NOTE: The provenance of this information is unknown; the details are obtained solely from third party information.

Directory traversal vulnerability in Advanced Guestbook 2.4.2 allows remote attackers to bypass .htaccess settings, and execute arbitrary PHP local files or read arbitrary local templates, via a .. (dot dot) in a lang cookie, followed by a filename without its .php extension, as demonstrated via a request to index.php.

Advanced Guestbook 2.4.2 allows remote attackers to obtain sensitive information via an invalid (1) GB_TBL parameter to (a) lang/codes-english.php or (b) image.php, which reveal the database name; (2) an invalid GB_DB parameter to index.php, coupled with a ../index lang cookie, which reveals the installation path; or (3) a direct request to index.php with no parameters or cookies, which reveals the installation path.
