A serious—and potentially embarrassing—issue has recently been reported by a few Skype users. Apparently, after applying the June 2012 update of Skype (ver. 184.108.40.206), users have experienced issues where IMs they send are being randomly forwarded to other people on their contact lists.
Skype officially acknowledged the issue today on its blog and has explained the specific circumstances under how the error is replicated:
"Based on recent Skype customer forum posts and our own investigation over the past couple of days, we have identified a bug that we are working hard to fix. This issue occurs only when a user's Skype client crashes during a Skype IM session, which may in some cases result in the last IM entered or sent prior to the crash being delivered to a different IM contact after the Skype client is rebooted or logged in as a new user."
The post also stated that the company believes relatively few Skype users have experienced the issue. Unfortunately, that doesn't rectify the fact that it's a serious breach of privacy for those users who have had the problem. If you're one of these unfortunate souls, rest assured that Skype is rolling out a fix as soon as they have one.
