Skype users were sending IMs that were going to the wrong recipients, many of whom were not even their contacts. However, the VoIP service previously denies it is a big issue and insists it affects just "small number of users" and called the pesky bug a "very rare occurrence."
The issue arose when a user's Skype program crashes while sending an instant messages (IM), which causes the message to go to the incorrect recipient after they restart the program, it said.
The company said, "We are aware that in rare circumstances IM's between two contacts could be sent to an unintended third contact.
The bug affected version of Skype for Mac, Windows, Linux and Windows Phone. However, Skype officials say they believe that the number of users affected by the glitch is small because it occurs under certain conditions that does not happen often.
Skype is rolling out a repair within the next few days for a bug that resulted in instant messages once sent to the wrong contact.
Situation was first reported last week in a Skype forum user support. According to Skype, the issue occurs when the program crash during Skype instant messaging session, and would cause the last inserted or instant message sent before the crash that delivered a variety of IM contacts after Skype client rebooted or log in as a new user.
"Although we can not determine precisely how many users can be affected by this error, we believe that number is small, given the very specific circumstances under which the error occurs," according to a posted on the official Skype blog.
The flaw affected only certain versions of Skype, as Skype 5.10 for Windows, Skype 5.8 for Mac computers, Skype 4.0 for Linux and Skype 1.2 for Windows Phone. "With further investigation, we confirmed that not all Skype products are affected by this error as originally reported," according to Skype blog. "We can assure that users of Skype 5.9 for Windows, Skype 2.8 for Android and Skype 4.0 for iOS have not been affected. In addition, we have fixed File Sending the desktop version of Skype which is not possible to save files for users with a hard-disk drive in FAT32 format. "
