Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy easily misused). strcpy(name, path); data/cog-0.8.0/platform/os-compatibility.c:146:3: [4] (buffer) strcat: Does not check for buffer overflows when concatenating to destination [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or snprintf (warning: strncat is easily misused). strcat(name, template); data/cog-0.8.0/platform/os-compatibility.c:135:10: [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. path = getenv("XDG_RUNTIME_DIR"); data/cog-0.8.0/platform/cog-platform-drm.c:177:23: [2] (misc) open: 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? (CWE-362). drm_data.fd = open (device->nodes[DRM_NODE_PRIMARY], O_RDWR); data/cog-0.8.0/platform/cog-platform-drm.c:531:12: [2] (misc) open: 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?

Make sure destination can always hold the source data. memcpy (&wl_data.touch.points[id], data/cog-0.8.0/platform/cog-platform-fdo.c:1322:5: [2] (buffer) memcpy: Does not check for buffer overflows when copying to destination (CWE-120). Make sure destination can always hold the source data. memcpy (&wl_data.touch.points[id], data/cog-0.8.0/platform/cog-platform-fdo.c:1360:5: [2] (buffer) memcpy: Does not check for buffer overflows when copying to destination (CWE-120). Make sure destination can always hold the source data. memcpy (&wl_data.touch.points[id], data/cog-0.8.0/platform/os-compatibility.c:75:7: [2] (tmpfile) mkstemp: Potential for temporary file vulnerability in some circumstances. Some older Unix-like systems create temp files with permission to write by all by default, so be sure to set the umask to override this. Also, some older Unix systems might fail to use O_EXCL when opening the file, so make sure that O_EXCL is used by the library (CWE-377). fd = mkstemp(tmpname); data/cog-0.8.0/platform/cog-im-context-fdo-v1.c:68:20: [1] (buffer) strlen: Does not handle strings that are not \0-terminated; if given one it may perform an over-read (it could cause a crash if unprotected) (CWE-126). unsigned len = strlen (text); data/cog-0.8.0/platform/cog-im-context-fdo-v1.c:294:14: [1] (buffer) strlen: Does not handle strings that are not \0-terminated; if given one it may perform an over-read (it could cause a crash if unprotected) (CWE-126). p += strlen (p) + 1; data/cog-0.8.0/platform/cog-im-context-fdo.c:64:15: [1] (buffer) strlen: Does not handle strings that are not \0-terminated; if given one it may perform an over-read (it could cause a crash if unprotected) (CWE-126). int len = strlen (text); data/cog-0.8.0/platform/os-compatibility.c:141:17: [1] (buffer) strlen: Does not handle strings that are not \0-terminated; if given one it may perform an over-read (it could cause a crash if unprotected) (CWE-126). name = malloc(strlen(path) + sizeof(template)); ANALYSIS SUMMARY: Hits = 13 Lines analyzed = 8796 in approximately 0.21 seconds (42292 lines/second) Physical Source Lines of Code (SLOC) = 6884 Hits@level = [0] 0 [1] 4 [2] 6 [3] 1 [4] 2 [5] 0 Hits@level+ = [0+] 13 [1+] 13 [2+] 9 [3+] 3 [4+] 2 [5+] 0 Hits/KSLOC@level+ = [0+] 1.88844 [1+] 1.88844 [2+] 1.30738 [3+] 0.435793 [4+] 0.290529 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
