Skype for Mac contains a format string vulnerability in the handling of URIs, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Skype software provides telephone service over IP networks. There is a format string vulnerability in the NSRunAlertPanel function in the routines that handle Skype-specific URIs, such as skype://.
By sending a specially crafted URI to Skype, a remote, unauthenticated attacker may be able to execute arbitrary code with the privileges of the user. Such a URI can be sent to Skype by convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment). The attacker could also cause Skype to crash.
