Skype 3.6.0.248, and other versions before 3.8.0.139, uses a case-sensitive comparison when checking for dangerous extensions, which allows user-assisted remote attackers to bypass warning dialogs and possibly execute arbitrary code via a file: URI with a dangerous extension that uses a different case.Show less

Incomplete blacklist vulnerability in Skype 3.6.0.248, and other versions before 3.8.0.139, allows user-assisted remote attackers to bypass warning dialogs and possibly execute arbitrary code via a file: URI that ends in an executable extension that is not covered by the blacklist.Show less

Cross-zone scripting vulnerability in the Internet Explorer web control in Skype 3.6.0.244, and earlier 3.5.x and 3.6.x versions, on Windows allows user-assisted remote attackers to inject arbitrary web script or HTML in the Local Machine Zone via the Description and unspecified other metadata fields of a Metacafe movie submitted by Metacafe Pro to the Skype video gallery, accessible through a search within the (1) "Add video to chat" or (2) "Add video to mood" dialog, a different vector than CVE-2008-0454.Show less

Cross-zone scripting vulnerability in the Internet Explorer web control in Skype 3.1 through 3.6.0.244 on Windows allows remote attackers to inject arbitrary web script or HTML in the Local Machine Zone via the Full Name field of a reviewer of a business item entry, accessible through (1) the SkypeFind dialog and (2) a skype:?skypefind URI for the skype: URI handler.Show less

Cross-zone scripting vulnerability in the Internet Explorer web control in Skype 3.6.0.244, and earlier 3.5.x and 3.6.x versions, on Windows allows user-assisted remote attackers to inject arbitrary web script or HTML in the Local Machine Zone via the Title field of a (1) Dailymotion and possibly (2) Metacafe movie in the Skype video gallery, accessible through a search within the "Add video to chat" dialog, aka "videomood XSS."Show less

Unspecified vulnerability in Skype allows remote attackers to cause a denial of service (server hang) via unknown vectors related to sending long URIs, as claimed to be actively exploited on 20070817 using a "call to a specific number." NOTE: this identifier is for the en.securitylab.ru disclosure. According to the vendor, this issue is separate from the "sign-on issues" that reduced Skype service on 20070817, which appears to be a site-specific problem. As of 20070821, it is not clear whether this issue is simply a symptom of the larger sign-on problem.Show less

Format string vulnerability in the NSRunAlertPanel function in eBay Skype for Mac 1.5.*.79 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a malformed Skype URL, as originally reported to involve a null dereference.Show less

Integer overflow in Skype client before 1.4.x.84 on Windows, before 1.3.x.17 on Mac OS, before 1.2.x.18 on Linux, and 1.1.x.6 and earlier allows remote attackers to cause a denial of service (crash) via crafted network data with a large Object Counter value, which leads to a resultant heap-based buffer overflow.Show less

Buffer overflow in Skype for Windows 1.1.x.0 through 1.4.x.83 allows remote attackers to execute arbitrary code via (1) callto:// and (2) skype:// links, or (3) a non-standard VCARD, possibly due to an underlying error in the SysUtils.WideFmtStr Delphi routine.Show less

Buffer overflow in the handling of command line arguments in Skype 1.0.x.94 through 1.0.x.98 allows remote attackers to execute arbitrary code via a callto:// URL with a long non-existent username, a different vulnerability than CVE-2004-1777.Show less

A "range check error" in Skype for Windows before 0.98.0.28 allows local and remote attackers to cause a denial of service (application crash) via long command line arguments or a long callto:// URL, a different vulnerability than CVE-2004-1114.Show less
