However, to be able to turn Skype users into victims, an attacker needs to build a fake website and trick users into visiting the Web site, Security-Assessment.com security expert Brett Moore, who has public discovered the said flaw.
In addition, the attacker must know the location of the file he wants to steal, as well as be required to add the victim name to the contact list.
According to Moore, this vulnerability is present in all versions of Windows released so far. Users are recommended to upgrade to Skype 2.5, 2.5.x.79 or later, as well as Skype 2.0, 2.0.x.105.
This is the first security bulletin that Skype released in the last 7 months. Last year, the company announced three security bulletins, two of which were rated as high-risk and a low-level vulnerability.
