The update, which is only available manually, comes one month after researcher Gordon Maddern published a blog post warning about the dangers of this vulnerability to Mac users.
"Thee long and the short of it is that an attacker needs only to send a victim a message and they can gain remote control of the victims Mac. It is extremely wormable and dangerous," Maddern said.
Skype followed up with an advisory that simply references "security updates."
The issue is now fixed with Skype for Mac version 5.1.0.922. Because this requires a manual update, it important for Mac users to apply the patch via the "software update" feature.
