Description The following test case causes ASAN to report stack-buffer-overflow. It seems that the array is viewed as NULL terminated string and the library tries to read 4 bytes from it instead of 3. DOCTEST_T
Exploiting a buffer overflow allows an attacker to control or crash a process or to modify its internal variables. Buffer overflow always ranks high in the Common Weakness Enumeration (CWE) andSANS Top 25 Most Dangerous Software Errors. A classic buffer overflow is specified as CWE-120 in the ...
