Abstract: Data is retrieved from a linked-list by locking the linked-list, retrieving data from an element in the linked-list, advancing to a subsequent element in the linked-list while a breakpoint is not encountered and marking the subsequent element as “in-use” when a breakpoint is encountered. A reference to the subsequent element is then created before the linked-list is unlocked.

Abstract: An embodiment of the invention provides an apparatus and method for automatic detection of a vulnerability exploit. The apparatus and method are configured to post a security vulnerability warning indicating a vulnerability of software; provide an exploit detector; and use the exploit detector to detect an attempted exploit that targets the vulnerability.

Abstract: A method for controlling connections from an IP entity to a server. Initially, a limit count, representing a number of concurrently allowable connections between the IP entity and the server, is determined. When an incoming IP packet is received, the packet is processed to determine the source and destination IP addresses for the packet. An entry is then created in a limit table for the IP entity, if no entry for that IP entity exists in the table. A determination is made as to whether a pending connection should be allowed for the packet, by referring to the limit count and the entry in the limit table. The connection is allowed, and the limit count for the entry is incremented, if the attempted connection would not exceed the limit count for the IP entity; otherwise, the packet is blocked if the attempted connection would exceed the limit count for the IP entity.
