Summary
Added O_CLOEXEC flag when opening files to ensure that file descriptors are automatically closed when executing child processes, thus preventing potential file descriptor leaks.
Changes Made:
Modified the open function to include the O_CLOEXEC flag when opening files.
Potential Scenarios:
Executing child processes: When a parent process opens a file and then spawns a child process, there is a possibility that the child process inherits the open file descriptors. Without the O_CLOEXEC flag, these file descriptors may remain open in the child process, leading to resource leaks and potential security vulnerabilities.
