StackShield is also implemented as a compile-time modi cation, but is otherwise unlike canary-based approaches The tool stores a copy of the return address to a second location at the beginning of the static data section when a function s stack frame is created, allows the function to execute normally, and loads the stored copy immediately before returning The advantage of this approach is that it prevents, rather than merely detecting, certain classes of buffer over ow exploits; this allows a protected program to continue execution in the face of attack The capability to continue execution might be desirable in programs for which uptime is a priority Unfortunately, without comparing the actual and stored return addresses, there is no way to identify when an exploit is attempted This makes it easier for an attacker to exploit a vulnerability that relies on overwriting a value other than the return address Exploits are often far from precise and the return address might be overwritten accidentally, but StackShield will allow the program to continue to execute, which gives the attacker more chances for success To counter this problem, StackShield can also be con gured to compare the original and stored values for inconsistencies and terminate the program if one is detected, but this mode of operation negates its primary advantage over canary-based approaches The fact that all solutions aside from native non-executable memory segments incur signi cant overhead is unavoidable, but the extent of this overhead is dif cult to gauge in the general case For example, StackGuard s authors have published data suggesting an overhead of approximately 15%, but this value varies signi cantly depending on the program [Cowan, 1998] For the kinds of programs that are typically written in C and C++, even a small performance penalty might simply be unacceptable As with the decision to use a safe language or implement rigorous bounds checking, you must weigh the trade-offs between the increased security that each of the solutions offers and the necessary costs involved in using them.

Virtual Execution Environments As with compiler-based techniques, solutions based on virtual execution environments attempt to address buffer over ow exploits dynamically at the latest point possible: the transition from valid code into malicious code Instead of protecting the return address and other pointers in memory, this approach tackles the problem from the other direction Tools based on virtual execution environments consider whether the target instruction in each jump should be executed To gain an instruction-level view of a program s execution, these solutions add a layer between the program and its execution environment by running it inside a specially designed virtual machine (VM) The VM identi es anomalous behavior in the sequence of instructions executed at runtime To combat exploits that involve injecting malicious code, the determination of whether to allow the execution of an instruction is based on its origin, which is classified as from the original image on disk and unmodified, dynamically generated but unmodified since generation, or as code that has been modified For exploits that invoke code already on the server in a malicious way, such as arc injection or return-into-libc attacks, virtual execution environments also allow control transfers to be specifically restricted by source, destination, and type of transfer Finally, both classes of checks are made more secure by the provision of uncircumventable sandboxing, which prevents the introduction of changes in control that bypass security checks The only commercially available implementation of a virtual execution environment that attempts to addresses security vulnerabilities is sold by Determina (http://wwwdeterminacom) The potential bene ts of the approach are obvious: No modi cation to the existing development process, compilation, or binary itself is required, and security checks are enforced in a exible fashion On the downside, because the protected program must run in a virtual environment with many of its instructions incurring a monitoring overhead, performance costs are hard to predict Hardened System Libraries Another approach to dynamic buffer over ow protection involves modifying the system libraries that a program links in to add safety checks to buffer over ow prone operations, such as some of the string-manipulation functions we discuss in 6 Solutions developed by Avaya, known as Libsafe and Libverify, combine a security-reinforced set of common string- and buffer-manipulation libraries and a compiler-based approach similar to.

This method tests whether the bounding sphere is empty A bounding sphere is empty if it is null (either by construction or as the result of a null intersection) or if its volume is negative A bounding sphere with a volume of zero is not empty
