Technical details
A heap-based out-of-bounds write exists in the `parse_browser` function within `src/browsers.c`. The vulnerability is triggered when GoAccess processes a User-Agent string where a short browser keyword (like 'Edg/') precedes the 'Opera' keyword. The code incorrectly assumes the 'Opera' token starts at the beginning of the buffer and performs a `memmove` to a fixed offset (match + 5), resulting in a 1-to-4 byte write beyond the allocated heap buffer. An unauthenticated remote attacker can exploit this by sending a crafted HTTP request to a web server whose logs are subsequently analyzed by GoAccess. This issue is fixed in version 1.11.
