Technical Analysis
libansilove versions 1.3.0 through 1.4.2 contain a NULL pointer dereference vulnerability in the ansilove_xbin() function. An attacker can supply a crafted XBIN file that sets the 512-character flag without the custom-font flag, causing the drawchar() function to index a NULL high_font_data_xbin pointer. This results in a crash of the affected application.
Potential Impact
The vulnerability allows an attacker with local access to cause a denial of service by crashing applications that use libansilove to process malicious XBIN files. There is no indication of code execution or data corruption beyond process termination.
