Skype for Windows 1.2.0.0 to 1.2.0.46 allows local users to bypass the identity check for an authorized application, then call arbitrary Skype API functions by modifying or replacing that application.
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.
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.
