Use a more secure technique for acquiring random values. a = 1.2 * drand48() - 0.1; data/kivy-1.11.0/kivy/lib/libtess2/Source/tess.c:177:36: [3] (random) drand48: This function is not sufficiently random for security-related functions such as key and nonce creation (CWE-327). Use a more secure technique for acquiring random values. #define S_UNIT_X (RandomSweep ?

(2*drand48()-1) : 0.0) data/kivy-1.11.0/kivy/lib/gstplayer/_gstplayer.h:39:2: [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 eventname[15]; data/kivy-1.11.0/kivy/lib/gstplayer/_gstplayer.h:99:4: [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(dstbuffer, srcbuffer, width3); data/kivy-1.11.0/kivy/lib/gstplayer/_gstplayer.h:134:2: [2] (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). Risk is low because the source is a constant string. strcpy(data->eventname, "pull-sample"); data/kivy-1.11.0/kivy/lib/gstplayer/_gstplayer.h:151:2: [2] (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). Risk is low because the source is a constant string. strcpy(data.eventname, "pull-preroll"); data/kivy-1.11.0/kivy/core/window/window_x11_core.c:251:20: [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). textprop.nitems = strlen(title); ANALYSIS SUMMARY: Hits = 8 Lines analyzed = 8268 in approximately 0.56 seconds (14675 lines/second) Physical Source Lines of Code (SLOC) = 5331 Hits@level = [0] 6 [1] 1 [2] 4 [3] 3 [4] 0 [5] 0 Hits@level+ = [0+] 14 [1+] 8 [2+] 7 [3+] 3 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 2.62615 [1+] 1.50066 [2+] 1.31307 [3+] 0.562746 [4+] 0 [5+] 0 Dot directories skipped = 3 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
