Blue Coat Authentication and Authorization Agent Remote Overflow

critical Nessus Plugin ID 68928


The remote host has an authentication application installed that is affected by a code execution vulnerability.


The version of Blue Coat Authentication and Authorization Agent installed on the remote Windows host is earlier than build 60258. It is, therefore, potentially affected by a stack-based buffer overflow vulnerability when handling specially crafted TCP packets on port 16102. By exploiting this flaw, a remote, unauthenticated attacker could execute arbitrary code on the remote host subject to the privileges of the user running the affected application.


Upgrade to build 60258 or later.
