A code sanitizer is a programming tool that detects bugs in the form of undefined or suspicious behavior by a compiler inserting instrumentation code at runtime. The class of tools was first introduced by Google's AddressSanitizer (or ASan) of 2012, which uses directly mapped shadow memory to detect memory corruption such as buffer overflows or accesses to a dangling pointer (use-after-free).
A static code analysis solution with many integration options for the automated detection of complex security vulnerabilities. SAST Online: 2022-03-07 (1.1.0) No; proprietary — — Java — — — Kotlin, APK: Check the Android Source code thoroughly to uncover and address potential security concerns and vulnerabilities.
John Regehr is a computer scientist specializing in compiler correctness and undefined behavior.As of 2016, he is a professor at the University of Utah.He is best known for the integer overflow sanitizer which was merged into the Clang C compiler, [1] the C compiler fuzzer Csmith, [2] [3] and his widely read blog Embedded in Academia.
It is the responsibility of the programmer to write code that never invokes undefined behavior, although compiler implementations are allowed to issue diagnostics when this happens. Compilers nowadays have flags that enable such diagnostics, for example, -fsanitize=undefined enables the "undefined behavior sanitizer" in gcc 4.9 [3] and in clang ...
Canaries or canary words or stack cookies are known values that are placed between a buffer and control data on the stack to monitor buffer overflows. When the buffer overflows, the first data to be corrupted will usually be the canary, and a failed verification of the canary data will therefore alert of an overflow, which can then be handled, for example, by invalidating the corrupted data.
Google Closure Tools [3] was a set of tools built with the goal of helping developers optimize rich web applications with JavaScript. It was developed by Google for use in their web applications such as Gmail, Google Docs and Google Maps. [4] As of Aug 1, 2024 the Closure Library has been sunset, for not "meeting the needs of modern JavaScript ...
Computing the code coverage of a test identifies code that is not tested; not covered by a test. Although this analysis identifies code that is not tested it does not determine whether tested coded is adequately tested. Code can be executed even if the tests do not actually verify correct behavior. Gcov is the GNU source code coverage program.
Caja (pronounced / ˈ k ɑː h ɑː / KAH-hah) [1] was a Google project for sanitizing third party HTML, CSS and JavaScript. On January 31, 2021, Google archived the project due to known vulnerabilities and lack of maintenance to keep up with the latest web security research, recommending instead the Closure toolkit .
