Description:
A vulnerability has been discovered in Skype, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error in Skype4COM.dll within the "skype4com" URI handler when processing short strings. This can be exploited to cause a limited heap-based buffer overflow as a longer string may be copied into a heap-based buffer previously allocated based on the length of the supplied URI.
Successful exploitation allows execution of arbitrary code when a user e.g. visits a malicious website.
The vulnerability is confirmed in Skype 3.5.0.239. Other versions prior to 3.6.0.216 may also be affected.
