An Adobe spokesman did not disagree but downplayed any outbreak.
Storms said Adobe released few details about this latest vulnerability, probably to ward off the potential for further exploits. Adobe said in its advisory that is has received reports of exploits appearing in the wild.
Jason Lam, a senior security analyst at a Canada-based financial institution and a handler for the SANS Internet Storm Center, warned of an increase in compromised websites being used to distribute the exploit. "This is likely to appear in a malware-spreading website near you soon given the track record of the botnet operators," he wrote on the Storm Center's blog. "Suggest [you] update this one as soon as possible."
Adobe Reader and Acrobat versions 7.1.0 are not affected.
