If you have a very large (millions of lines of code) codebase, written in a memory-unsafe programming language (such as C or C++), you can expect at least 65% of your security vulnerabilities to be caused by memory unsafety. He based this claim on data on operating systems including ...
“Most critical open-source projects analyzed, even those written in memory-safe languages, potentially contain memory safety vulnerabilities. This can be caused by direct use of memory-unsafe languages or external dependency on projects that use memory-unsafe languages,” the report stated. “Addition...
"Even with a memory safe language, memory management is not entirely memory safe. Most memory safe languages recognize that software sometimes needs to perform an unsafe memory management function to accomplish certain tasks. As a result, classes or functions are available that a...

As explained earlier (refer to Section 2.1), unsafe languages do not have explicit memory checks. The defense methods in this sub-category aim to add memory checks intelligently to ensure a minimal performance overhead. Serebryany et al. [96] proposed a tool called AddressSanitizer to reduce ...
The code is written in an unsafe programming language (C/C++) Image: Google While software companies have tried before to fix C and C++'s memory management problems, Mozilla has been the one who made a breakthrough by sponsoring, promoting and heavily adopting the Rust programming language in...
often leading to runtime explosions. C relies on the programmer to never make a mistake. Given that our goal was to make Swift “safe by default,” this approach was quickly discarded for general use. However, APIs likeUnsafePointerallow you to explicitly opt-in to unsafety when this power...
None of these techniques require unsafe code. Used wisely, you can get performance characteristics from safe code that was previously only possible by using unsafe techniques. You can try the techniques yourself in the tutorial on reducing memory allocations....

The tech giant said focusing onSafe Codingfor new features not only reduces the overall security risk of a codebase, but also makes the switch more "scalable and cost-effective." Eventually, this leads to a drop in memory safety vulnerabilities as new memory unsafe development slows down after...
