It 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. g_get_tmp_dir(), data/pcmanfm-1.3.1/src/app-config.c:596:9: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use functions that limit length, or ensure that the size is larger than the maximum possible length. char wpn_buf[32]; data/pcmanfm-1.3.1/src/app-config.c:710:32: [2] (integer) atoi: Unless checked, the resulting number can exceed the expected range (CWE-190).
