Microsoft Skype 'MSFTEDIT.DLL' Buffer Overflow Vulnerability

Microsoft Skype is prone to a local buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data.

Attackers can exploit this issue to crash the application, resulting in a denial-of-service condition. Due to the nature of this issue, code execution may be possible but this has not been confirmed.

Microsoft Skype 7.2, 7.35,,,, and 7.36 are vulnerable; other versions may also be affected.
