Buffer Overflow

Dynamic Buffer Overflow Detection

The capabilities of seven dynamic buffer overflow detection tools (Chaperon, Valgrind, CCured, CRED, Insure++, ProPolice and TinyCC) are evaluated in this paper. These tools employ different approaches to runtime buffer overflow detection and range from commercial products to opensource gcc-enhancements. A comprehensive testsuite was developed consisting of specifically-designed test cases and ...

Buffer overflow and format string overflow vulnerabilities

Buffer overflow vulnerabilities are among the most widespread of security problems. Numerous incidents of buffer overflow attacks have been reported and many solutions have been proposed, but a solution that is both complete and highly practical is yet to be found. Another kind of vulnerability called format string overflow has recently been found, and though not as popular as buffer overflow, ...

Buffer Overflow Analysis for C

Buffer overflow detection and mitigation for C programs has been an important concern for a long time. This paper defines a string buffer overflow analysis for C. The key ideas of our formulation are (a) separating buffers from the pointers that point to them, (b) modelling buffers in terms of sizes and sets of positions of null characters, and (c) defining stateless functions to compute the se...
