Descriptions

Heap-based buffer overflow in WeeChat 0.3.6 through 0.3.9 allows remote attackers to cause a denial of service (crash or hang) and possibly execute arbitrary code via crafted IRC colors that are not properly decoded.

Desbordamiento de búfer basado en memoria dinámica en weechat v0.3.6 a hasta v0.3.9 permite a atacantes remotos provocar una denegación de servicio (caída o bloqueo) y posiblemente ejecutar código arbitrario a través de colores IRC hechos a mano que no están debidamente decodificados.

Two vulnerabilities have been found in WeeChat, the worst of which may allow execution of arbitrary code. Versions less than 0.3.9.2 are affected.
