Descriptions

The Gluster file system through versions 3.12 and 4.1.4 is vulnerable to a buffer overflow in the 'features/index' translator via the code handling the 'GF_XATTR_CLRLK_CMD' xattr in the 'pl_getxattr' function. A remote authenticated attacker could exploit this on a mounted volume to cause a denial of service.

El sistema de archivos Gluster hasta las versiones 3.12 y 4.1.4 es vulnerable a un desbordamiento de búfer en el traductor "features/index" mediante el código que maneja el xattr "GF_XATTR_CLRLK_CMD" en la función "pl_getxattr". Un atacante autenticado remoto podría explotar esta vulnerabilidad en un volumen montado para provocar una denegación de servicio (DoS).

A buffer overflow was found in strncpy of the pl_getxattr() function. An authenticated attacker could remotely overflow the buffer by sending a buffer of larger length than the size of the key resulting in remote denial of service.
