…y cause overflow This autofix addresses a potential buffer overflow vulnerability caused by calling std::snprintf with a size argument larger than the destination buffer capacity. The fix adjusts the size argument from 11 to 10, matching the actual allocated size of the 'a2' array. This ensures that snprintf does not write beyond the end of the buffer, preventing possible memory corruption, segmentation faults, or undefined behavior. No functional logic or dependencies were changed. The update aligns the implementation with secure C++ coding standards and mitigates CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-131 (Incorrect Calculation of Buffer Size).

Potential fix for https://github.com/AndresMaqueo/codeql-coding-standards/security/code-scanning/101
To fix this error, update the call to
std::snprintf(a2, 11, ...)so the size argument matches the allocated size ofa2, which is 10. This change ensures thatsnprintfwill not write past the end of the buffer, preventing a potential buffer overflow. No imports or additional definitions are necessary; simply change the argument from11to10on line 45. All other uses ofa2remain unchanged.Suggested fixes powered by Copilot Autofix.
