Adobe said it will soon release a patch for a bug in Flash that has been used for more than a month by attackers to poison Windows and Mac users' clipboards with URLs to malicious sites.
The changes will be rolled out in Flash 10, which Adobe's security program manager David Lenoe said would be released "soon".
In August, security researchers reported malicious scripts in Flash-based ads on legitimate sites. The scripts abused the 'setClipboard' command in Flash to repeatedly infect users' clipboards with URLs pushing fake security software. The scammers hoped that some of those users would paste the URL into their browser's address bar, and once at the phony software site, would be duped into purchasing the bogus program. Users on several message boards, including Apple's support forum, reported the clipboard poisoning more than a month ago.
Lenoe acknowledged the attacks in an August 19 post to Adobe's security response team's blog, but at the time said only that the company was investigating "potential solutions". Adobe, however, has not patched the current production version of Flash 9.
Adobe first unveiled a beta of Flash 10 in May, and shifted to a more polished release candidate a week ago. Flash 10 can be downloaded in its current form from Adobe's site.
It's unclear, however, if the security changes that McCauley outlined have been integrated into Flash 10's release candidate. Adobe did not immediately respond to questions about what was included in the release candidate.
