Descriptions

The tcf_fill_node function in net/sched/cls_api.c in the netlink subsystem in the Linux kernel 2.6.x before 2.6.32-rc5, and 2.4.37.6 and earlier, does not initialize a certain tcm__pad2 structure member, which might allow local users to obtain sensitive information from kernel memory via unspecified vectors. NOTE: this issue exists because of an incomplete fix for CVE-2005-4881.

La función tcf_fill_node en net/sched/cls_api.c del subsistema netlink en el kernel de Linux v2.6.x hasta la v2.6.32-rc5, y v2.4.37.6 y anteriores, no inicializa un determinado miembro de la estructura tcm__pad2, lo que puede permitir a usuarios locales obtener información confidencial de la memoria del kernel a través de vectores de ataque sin especificar. NOTA: esta vulnerabilidad existe debido a una solución incompleta de CVE-2005-4881.

Kernel packages have been updated. It was discovered that the AX.25 network subsystem did not correctly check integer signedness in certain setsockopt calls. Jan Beulich discovered that the kernel could leak register contents to 32-bit processes that were switched to 64-bit mode. Dave Jones discovered that the gdth SCSI driver did not correctly validate array indexes in certain ioctl calls. Eric Dumazet and Jiri Pirko discovered that the TC and CLS subsystems would leak kernel memory via uninitialized structure members. Earl Chew discovered race conditions in pipe handling. There are about a dozen other issues also addressed.
