CVE-2026-55777

GoAccess is a real-time web log analyzer and interactive viewer that runs in a terminal in *nix systems or through the browser. Prior to 1.11, the parse_ios() function uses an attacker-controlled keyword-to-OS offset as both the source offset and copy length for memmove, allowing a crafted User-Agent in a processed access log to read up to approximately 4 KB beyond the heap allocation and conditionally crash GoAccess. This issue is fixed in version 1.11.

Summary		(es) GoAccess es un analizador de registros web en tiempo real y visor interactivo que se ejecuta en una terminal en sistemas nix o a través del navegador. Antes de la versión 1.11, la función parse_ios() utiliza un desplazamiento de palabra clave a SO controlado por el atacante como desplazamiento de origen y longitud de copia para memmove, permitiendo que un User-Agent manipulado en un registro de acceso procesado lea hasta aproximadamente 4 KB más allá de la asignación de memoria dinámica y bloquee GoAccess condicionalmente. Este problema está solucionado en la versión 1.11.
