Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy easily misused). strcpy(eret_esto_alg_str, argv[ctr + 1]); data/globus-xio-gridftp-driver-3.2/test/globus_gridftp_driver_test.c:70:50: [3] (buffer) getenv: Environment variables are untrustable input if they can be set by an attacker. They can have any content and length, and the same variable can be set more than once (CWE-807, CWE-20). Check environment variables carefully before using them. const char * cs = getenv("FTP_TEST_SOURCE_HOST"); data/globus-xio-gridftp-driver-3.2/test/globus_gridftp_driver_test.c:71:55: [3] (buffer) getenv: Environment variables are untrustable input if they can be set by an attacker.

Make sure destination can always hold the source data. memcpy(attr, &globus_l_xio_gridftp_attr_default, data/globus-xio-gridftp-driver-3.2/globus_xio_gridftp_driver.c:2440:5: [2] (buffer) memcpy: Does not check for buffer overflows when copying to destination (CWE-120).

Perform bounds checking, use functions that limit length, or ensure that the size is larger than the maximum possible length. char eret_esto_alg_str[ALG_NAME_LEN]; data/globus-xio-gridftp-driver-3.2/test/globus_gridftp_driver_test.c:235:14: [2] (misc) fopen: Check when opening files - can an attacker redirect it (via symlinks), force the opening of special file type (e.g., device files), move things around to create a race condition, control its ancestors, or change its contents?
