Summary

libansilove 1.3.0 through 1.4.2 contains a NULL pointer dereference in ansilove_xbin() that lets attackers crash applications with a crafted XBIN file. Setting the 512-character flag without the custom-font flag makes drawchar() index a NULL high_font_data_xbin pointer, which terminates the process. The weakness is CWE-476.
