Adobe released a security advisory about vulnerabilities found in its Adobe Reader and Acrobat softwares. The vulnerable versions are Adobe Reader 7.0.0-7.0.8 and Adobe Standard and Professional 7.0.0-7.0.8 on a Windows platform while using Internet Explorer.
By tricking potential victims into browsing a specially crafted web page, successful exploitation of the said vulnerabilities could allow remote code execution on affected users machine. There are no security patch available as of the moment but a workaround is provided by Adobe. Users are to delete the “AcroPDF.dll” in the Adobe installation directory or another way is to set the kill bit for the CLSID [CA8A9780-280D-11CF-A24D-444553540000]. (Using another browser can also be an option, as other browsers are not affected. However, the best way still is to delete the vulnerable DLL.)
