Rule:--Sid:3517--Summary:This event is generated when an attempt is made to exploit abuffer overflow associated with Computer Associates Licensesoftware.--Impact:A successful attack can cause a buffer overflow of the host andthe subsequent execution of arbitrary code.--Detailed Information:Computer Associates License software allows a site to maintain andhandle licenses for CA products.  A server runs the software tofacilitate this and it communicates with clients/agents on thenetwork. A vulnerability exists in the PUTOLF message that exchangesdata with a listening server or client.The PUTOLF message allocates fixed-sized buffers for some of the valuessupplied to it.  No validation is performed by the receiving host toensure that the data received fits in the allocated buffer(s).  If thereceived data cannot fit in the buffer, an overflow occurs and executionof arbitrary code on the vulnerable host is possible.--Affected Systems:CA License 1.0.15, 1.53-57, 1.60, 1.60.2, 1.60.3, 1.61, 1.61.1, 1.61.2,           1.61.8--Attack Scenarios:An attacker can craft a PUTOLF message with overly long data, causinga buffer overflow on the vulnerable listening CA License server orclient.--Ease of Attack:Simple.--False Positives:None known.--False Negatives:None known.--Corrective Action:Upgrade to the most current non-affected version of the product.Apply the appropriate vendor supplied patches.--Contributors:Sourcefire Vulnerability Research TeamJudy Novak <judy.novak@sourcefire.com>--Additional ReferencesiDefense Advisory:http://www.idefense.com/application/poi/display?id=211&type=vulnerabilities--
