Descriptions

The ldm_frag_add function in fs/partitions/ldm.c in the Linux kernel before 2.6.39.1 does not properly handle memory allocation for non-initial fragments, which might allow local users to conduct buffer overflow attacks, and gain privileges or obtain sensitive information, via a crafted LDM partition table. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-1017.

La función ldm_frag_add de fs/partitions/ldm.c del kernel de Linux en versiones anteriores a la 2.6.39.1 no maneja apropiadamente la reserva de memoria para fragmentos no iniciales, lo que permite a usuarios locales realizar ataques de desbordamiento de buffer y escalar privilegios u obtener información confidencial a través de una tabla de particiones LDM. NOTA: esta vulnerabilidad se debe a una solución incompleta de CVE-2011-1017.
