Elazar Broad has discovered a vulnerability in MySpace Uploader Control, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error in the MySpace.Uploader.4.1 ActiveX control (MySpaceUploader.ocx) when handling strings assigned to certain properties (e.g. "Action", "ExtractIptc", and "ExtractExif"). This can be exploited to cause a stack-based buffer overflow by assigning an overly long (greater than 260 characters) string to the affected properties.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in MySpaceUploader.ocx version 126.96.36.199 and reported in version 188.8.131.52. Other versions may also be affected.
Solution: Update to version 184.108.40.206.
