Buffer overflow attacks are serious security threats to modern computer systems. Prior works against buffer overflow attacks may require users to patch the source codes, rebuild programs, modify the operating system or the augments of hardware architecture, and thus often result in performance ...
Secure Bit: Transparent, Hardware Buffer-Overflow Protection We propose a minimalist, architectural approach, Secure Bit (patent pending), to protect against buffer overflow attacks on control data (return-address an...

GuardStack is designed to mitigate only a specific type of vulnerability, namely stack buffer overflow. More important, using GuardStack by itself against this vulnerability may not provide a high degree of protection because there are ways for an attacker to go around it:...
A POP buffer overflow attack occurs when a remote attacker attempts to gain root access of a POP server by overflowing an internal buffer on the server. ISA Server Preconfigured Attack Protection ISA Server includes preconfigured protection against specific attacks. This includes spoof detection and br...

Though StackGuard may be effective in preventing stack-buffer overflow attacks it has certain limitations as well: An information disclosure flaw in a different part of the program could disclose the global __stack_chk_guard value. This would allow an attacker to write the correct canary value ...
2.9.9 Buffer Overflow Attack Mitigation Starting with the 2.6.x kernel releases, Linux offers Address Space Layout Randomization (ASLR) and the No-eXecute (NX bit) for mitigation of buffer overflow attacks. For more information, see:
Data execution prevention (DEP) prevents memory that wasn't explicitly allocated as executable from being executed. DEP helps protect against an attacker injecting malicious code into the process, such as through a buffer overflow, and then executing that code. ...
In this way, the secure memory access logic 150 enables the computing device 100 to provide indirect address security against buffer overflow attacks and similar exploits. Embodiments of the indirect address security technologies disclosed herein can also be used for software debugging purposes or as ...
