Security issues in the C language mainly arise from its low-level nature and lack of built-in safeguards against common vulnerabilities like buffer overflows, pointer arithmetic errors, and format string vulnerabilities. These can lead to memory corruption, code injection, and other exploits if not carefully managed.
