Build a business case: developing custom apps

Security flaws in an ActiveX control used in MySpace upload images onto the social networking sites leave users open to attack. Facebook users may also be at risk.

A buffer overflow vulnerability in Aurigma's Image Uploader Control Library might be used to compromise a user's system. The affected control is used for uploading images onto social networking sites using Microsoft's Internet Explorer. Users might be vulnerable if tricked into visiting a specially crafted web page that exploits the vulnerability.

The flaw was first reported by Elazar Broad on a full disclosure mailing list, who said that the vulnerable control was used by MySpace. Facebook also reportedly repackages the Aurigma control, though which version it uses is unclear. Broad reported the problem to Aurigma.

Aurigma, a Washington-based software developer, acknowledged that version 4.5.70 of its control was vulnerable but said that later versions of its software were safe from attack. It didn't comment on the use of its software on social networking sites.

Security notification firm Secunia advises MySpace users to set the "kill-bit" for the affected ActiveX control, which is known as MySpaceUploader.ocx version 1.0.0.4. Advise from Microsoft on how to disable vulnerable ActiveX controls can be found here. ®
