Descriptions

The actions implementation in the network queueing functionality in the Linux kernel before 2.6.36-rc2 does not properly initialize certain structure members when performing dump operations, which allows local users to obtain potentially sensitive information from kernel memory via vectors related to (1) the tcf_gact_dump function in net/sched/act_gact.c, (2) the tcf_mirred_dump function in net/sched/act_mirred.c, (3) the tcf_nat_dump function in net/sched/act_nat.c, (4) the tcf_simp_dump function in net/sched/act_simple.c, and (5) the tcf_skbedit_dump function in net/sched/act_skbedit.c.

La implementación de acciones en la funcionalidad de encolado de red en el kernel Linx anterior a v2.6.36-rc2 no inicializa apropiadamente ciertos miembros de estructura cuando se realizan acciones de volcado, lo que permite a usuarios locales obtener información potencialmente sensible de la memoria del kernel a través de vectores relacionados con (1) la funcion tcf_gact_dump en net/sched/act_gact.c, (2) la funcion tcf_mirred_dump en net/sched/act_mirred.c, (3) la funcion tcf_nat_dump en net/sched/act_nat.c, (4) la funcion tcf_simp_dump en net/sched/act_simple.c, y (5) la funcion tcf_skbedit_dump en net/sched/act_skbedit.c.
