Описание
The epoll implementation in the Linux kernel 2.6.37.2 and earlier does not properly traverse a tree of epoll file descriptors, which allows local users to cause a denial of service (CPU consumption) via a crafted application that makes epoll_create and epoll_ctl system calls.
Отчет
This issue affected the versions of Linux kernel as shipped with Red Hat Enterprise Linux 4, 5, 6, and Red Hat Enterprise MRG. It was addressed in Red Hat Enterprise Linux 5 and 6 via RHSA-2012:0150 and RHSA-2012:0862 respectively. There is no plan to address this flaw in Red Hat Enterprise Linux 4. Future updates may address this issue in Red Hat Enterprise MRG.
