Adobe patches Reader flaw
PDF flaw affects affect older, infirm package
Security watchers are warning of a critical flaw affecting older versions of Adobe Reader.
Successful exploitation against the Adobe Reader flaw would involve tricking users into opening a laced pdf file. The flaw only affects users of Adobe Reader 8, which was replaced by Adobe Reader 9 in June 2008. Nonetheless Core argues that many users are still running older versions of the software and are therefore at risk of attack.
