Описание
The perf_swevent_init function in kernel/events/core.c in the Linux kernel before 3.8.9 uses an incorrect integer data type, which allows local users to gain privileges via a crafted perf_event_open system call.
Отчет
This issue does not affect the kernel packages as shipped with Red Hat Enterprise Linux 5 because we did not backport upstream commit b0a873eb that introduced this issue. This issue was addressed in Red Hat Enterprise Linux 6 via RHSA-2013:0830 (https://rhn.redhat.com/errata/RHSA-2013-0830.html), Red Hat Enterprise Linux 6.1 Extended update support via RHSA-2013:0841 (https://rhn.redhat.com/errata/RHSA-2013-0841.html), Red Hat Enterprise Linux 6.2 Extended update support via RHSA-2013:0840 (https://rhn.redhat.com/errata/RHSA-2013-0840.html), Red Hat Enterprise Linux 6.3 Extended Update Support via RHSA-2013:0832 (https://rhn.redhat.com/errata/RHSA-2013-0832.html), and Red Hat Enterprise MRG 2 via RHSA-2013:0829 (https://rhn.redhat.com/errata/RHSA-2013-0829.html). Red Hat Enterprise Linux 6.0 was not affected by this flaw. Refer to https://access.redhat.com/site/solutions/373743 for further information.
