FINAL RESULTS:
data/kvmtool-0.20170904/virtio/9p.c:360:8: [5] (race) chmod:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchmod( ) instead.
ret = chmod(full_path, mode & 0777);
data/kvmtool-0.20170904/virtio/9p.c:401:8: [5] (race) chmod:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchmod( ) instead.
ret = chmod(full_path, mode & 0777);
data/kvmtool-0.20170904/virtio/9p.c:738:9: [5] (race) chmod:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchmod( ) instead.
ret = chmod(fid->abs_path, p9attr.mode);
data/kvmtool-0.20170904/virtio/9p.c:907:8: [5] (race) readlink:
This accepts filename arguments; if an attacker can move those files or
change the link content, a race condition results. Also, it does not
terminate with ASCII NUL. (CWE-362, CWE-20). Reconsider approach.
ret = readlink(fid->abs_path, target_path, PATH_MAX - 1);
data/kvmtool-0.20170904/virtio/9p.c:977:8: [5] (race) chmod:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchmod( ) instead.
ret = chmod(full_path, mode & 0777);
data/kvmtool-0.20170904/guest/init.c:63:7: [4] (race) access:
This usually indicates a security flaw. If an attacker can change anything
along the path between the call to access() and the file's actual use
(e.g., by moving files), the attacker can exploit the race condition
(CWE-362/CWE-367!). Set up the correct permissions (e.g., using setuid())
and try to open the file directly.
if (access("/virt/sandbox.sh", R_OK) == 0)
data/kvmtool-0.20170904/hw/pci-shmem.c:339:3: [4] (buffer) strcpy:
Does not check for buffer overflows when copying to destination [MS-banned]
(CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
easily misused).
strcpy(handle, default_handle);
data/kvmtool-0.20170904/include/kvm/util.h:40:71: [4] (format) printf:
If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.

data/kvmtool-0.20170904/include/kvm/util.h:42:64: [4] (format) printf:

extern int pr_err(const char *err, ...) __attribute__((format (printf, 1, 2)));
data/kvmtool-0.20170904/include/kvm/util.h:43:69: [4] (format) printf:
If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.
extern void pr_warning(const char *err, ...) __attribute__((format (printf, 1, 2)));
data/kvmtool-0.20170904/include/kvm/util.h:44:66: [4] (format) printf:
