A new zero day flaw in Windows XP and Windows Server 2003 is being exploited in the wild to bypass the sandbox on unpatched versions of Adobe Reader, security firm FireEye has reported.
According to the firm's analysis, the vulnerability allows for a standard user running XP SP3 to elevate privileges to admin level, allowing a targeted attack on users running Reader versions 9.5.4, 10.1.6, 11.0.02 and before using a malicious PDF.
"An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full administrative rights," said Microsoft in a separate advisory (2914486).
Dunno if this vulnerability exists in other readers--I use PDF XChange Viewer.
