Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/tv-fonts-1.1/code/exp-gfx.c Examining data/tv-fonts-1.1/code/x11font.c Examining data/tv-fonts-1.1/code/x11font-o.c FINAL RESULTS: data/tv-fonts-1.1/code/exp-gfx.c:1175:12: [4] (format) snprintf: If format strings can be influenced by an attacker, they can be exploited, and note that sprintf variations do not always \0-terminate (CWE-134). Use a constant for the format specification. size += snprintf(title + size, sizeof(title) - size - 1, data/tv-fonts-1.1/code/exp-gfx.c:1180:12: [4] (format) snprintf: If format strings can be influenced by an attacker, they can be exploited, and note that sprintf variations do not always \0-terminate (CWE-134). Use a constant for the format specification. size += snprintf(title + size, sizeof(title) - size - 1, data/tv-fonts-1.1/code/exp-gfx.c:79:4: [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(p, wstfont2_bits + (j + i) * wstfont2_width / 8, data/tv-fonts-1.1/code/exp-gfx.c:82:2: [2] (buffer) memcpy: Does not check for buffer overflows when copying to destination (CWE-120).

Perform bounds checking, use functions that limit length, or ensure that the size is larger than the maximum possible length. char title[80]; data/tv-fonts-1.1/code/x11font-o.c:58:7: [2] (misc) fopen: 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). fp = fopen(filename,"w"); data/tv-fonts-1.1/code/x11font.c:59:7: [2] (misc) fopen: 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?
