Use a constant for the format specification. vfprintf(logprops.dst, msg, args); data/xdg-desktop-portal-wlr-0.1.0/src/screenshot/screenshot.c:24:3: [4] (shell) execvp: This causes a new program to execute and is difficult to use safely (CWE-78). try using a library call that implements the same functionality if available. execvp("grim", argv); data/xdg-desktop-portal-wlr-0.1.0/src/core/main.c:47:11: [3] (buffer) getopt_long: Some older implementations do not protect against internal buffer overflows (CWE-120, CWE-20).

Perform bounds checking, use functions that limit length, or ensure that the size is larger than the maximum possible length. char uri[strlen(path) + strlen(uri_prefix) + 1]; data/xdg-desktop-portal-wlr-0.1.0/src/screencast/pipewire_screencast.c:148:18: [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). randname(name + strlen(name) - 6); data/xdg-desktop-portal-wlr-0.1.0/src/screencast/wlr_screencast.c:48:19: [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). randname(name + strlen(name) - 6); data/xdg-desktop-portal-wlr-0.1.0/src/screenshot/screenshot.c:64:11: [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). char uri[strlen(path) + strlen(uri_prefix) + 1]; data/xdg-desktop-portal-wlr-0.1.0/src/screenshot/screenshot.c:64:26: [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). char uri[strlen(path) + strlen(uri_prefix) + 1]; ANALYSIS SUMMARY: Hits = 11 Lines analyzed = 1858 in approximately 0.05 seconds (35427 lines/second) Physical Source Lines of Code (SLOC) = 1507 Hits@level = [0] 10 [1] 4 [2] 4 [3] 1 [4] 2 [5] 0 Hits@level+ = [0+] 21 [1+] 11 [2+] 7 [3+] 3 [4+] 2 [5+] 0 Hits/KSLOC@level+ = [0+] 13.935 [1+] 7.29927 [2+] 4.64499 [3+] 1.99071 [4+] 1.32714 [5+] 0 Dot directories skipped = 2 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
