Multiple vulnerabilities were identified in Skype, which could be exploited by remote attackers to execute arbitrary commands or cause a denial of service.
The first issue is due to a buffer overflow error when processing a specially crafted "callto://" or "skype://" URL, which could be exploited by attackers to execute arbitrary commands.
The second vulnerability is due to an error when importing non-standard VCARD files, which could be exploited by attackers to compromise a vulnerable system by convincing a user to import a malicious VCARD.
The third flaw is due to a heap overflow error when handling specially crafted network packets, which could be exploited by remote attackers to execute arbitrary commands or cause a denial of service.
