Because this makes the addresses unpredictable, it can prevent an attacker from reliably jumping to exploitable code.Įxamples include Address Space Layout Randomization (ASLR) and Position-Independent Executables (PIE). Run or compile the software using features or extensions that randomly arrange the positions of a program’s executable and libraries in memory. Examples include the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice.Ĭonsider adhering to the following rules when allocating and managing an application’s memory: Run or compile the software using features or extensions that automatically provide a protection mechanism that mitigates or eliminates buffer overflows.įor example, certain compilers and extensions provide automatic buffer overflow detection mechanisms that are built into the compiled code. These libraries provide safer versions of overflow-prone string-handling functions. Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.Įxamples include the Safe C String Library (SafeStr) by Messier and Viega, and the Strsafe.h library from Microsoft. Other languages, such as Ada and C#, typically provide overflow protection, but the protection can be disabled by the programmer.īe wary that a language’s interface to native code may still be subject to overflows, even if the language itself is theoretically safe. Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.įor example, many languages that perform their own memory management, such as Java and Perl, are not subject to buffer overflows.

The software writes data past the end, or before the beginning, of the intended buffer.

LibRaw::raw2image() in libraw_cxx.cpp has a heap-based buffer overflow.
