Summary
The icmp_check_sysrq function in net/ipv4/icmp.c in the kernel.org projects/rt patches for the Linux kernel, as used in the kernel-rt package before 3.10.0-327.22.1 in Red Hat Enterprise Linux for Real Time 7 and other products, allows remote attackers to execute SysRq commands via crafted ICMP Echo Request packets, as demonstrated by a brute-force attack to discover a cookie, or an attack that occurs after reading the local icmp_echo_sysrq file.

Summary
Red Hat Security Advisory: kernel-rt security, bug fix, and enhancement update
Notes
Topic
An update for kernel-rt is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.
Details
The kernel-rt packages contain the Linux kernel, the core of any Linux
operating system.
The following packages have been upgraded to a newer upstream version:
kernel-rt (3.10.0-327.22.1). This version provides a number of bug fixes
and enhancements, including:
* [netdrv] ixgbevf: fix spoofed packets with random MAC and use ether_addr_copy instead of memcpy
* [mm] mmu_notifier: fix memory corruption
* [mm] hugetlbfs: optimize when NUMA=n
* [mm] optimize put_mems_allowed() usage
* [x86] mm: suitable memory should go to ZONE_MOVABLE
* [fs] xfs: fix splice/direct-IO deadlock
* [acpi] tables: Add acpi_subtable_proc to ACPI table parsers
* [acpi] table: Add new function to get table entries
* [net] ipv6: Nonlocal bind
* [net] ipv4: bind ip_nonlocal_bind to current netns
(BZ#1335747)
Security Fix(es):
* A flaw was found in the way certain interfaces of the Linux kernel's
Infiniband subsystem used write() as bi-directional ioctl() replacement,
which could lead to insufficient memory security checks when being invoked
using the the splice() system call. A local unprivileged user on a system
with either Infiniband hardware present or RDMA Userspace Connection
Manager Access module explicitly loaded, could use this flaw to escalate
their privileges on the system. (CVE-2016-4565, Important)
* A race condition flaw was found in the way the Linux kernel's SCTP
implementation handled sctp_accept() during the processing of heartbeat
timeout events. A remote attacker could use this flaw to prevent further
connections to be accepted by the SCTP server running on the system,
resulting in a denial of service. (CVE-2015-8767, Moderate)
* A flaw was found in the way the realtime kernel processed specially
crafted ICMP echo requests. A remote attacker could use this flaw to
trigger a sysrql function based on values in the ICMP packet, allowing them
to remotely restart the system. Note that this feature is not enabled by
default and requires elevated privileges to be configured. (CVE-2016-3707,
Moderate)
Red Hat would like to thank Jann Horn for reporting CVE-2016-4565.
Bug Fix(es):
* Previously, configuration changes to the Hewlett Packard Smart Array
(HPSA) driver during I/O operations could set the phys_disk pointer to
NULL. Consequently, kernel oops could occur while the HPSA driver was
submitting ioaccel2 commands. An upstream patch has been provided to fix
this bug, and the oops in the hpsa_scsi_ioaccel_raid_map() function no
longer occurs. (BZ#1335411)
* In a previous code update one extra spin_lock operation was left
untouched. Consequently, a deadlock could occur when looping through cache
pages. With this update, the extra lock operation has been removed from
the source code and the deadlock no longer occurs in the described
situation. (BZ#1327073)

Summary
Red Hat Security Advisory: kernel-rt security and bug fix update
Notes
Topic
An update for kernel-rt is now available for Red Hat Enterprise MRG 2.5.
Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.
Details
The kernel-rt package contain the Linux kernel, the core of any Linux
operating system.
This update provides a build of the kernel-rt package for Red Hat
Enterprise MRG 2.5 that is layered on Red Hat Enterprise Linux 6, and
provides a number of bug fixes including:
* [netdrv] ixgbevf: fix spoofed packets with random MAC and use ether_addr_copy instead of memcpy
* [mm] mmu_notifier: fix memory corruption
* [mm] hugetlbfs: optimize when NUMA=n
* [mm] optimize put_mems_allowed() usage
* [x86] mm: suitable memory should go to ZONE_MOVABLE
* [fs] xfs: fix splice/direct-IO deadlock
* [acpi] tables: Add acpi_subtable_proc to ACPI table parsers
* [acpi] table: Add new function to get table entries
* [net] ipv6: Nonlocal bind
* [net] ipv4: bind ip_nonlocal_bind to current netns
(BZ#1332298)
Security Fix(es):
* A flaw was found in the way certain interfaces of the Linux kernel's
Infiniband subsystem used write() as bi-directional ioctl() replacement,
which could lead to insufficient memory security checks when being invoked
using the splice() system call. A local unprivileged user on a system
with either Infiniband hardware present or RDMA Userspace Connection
Manager Access module explicitly loaded, could use this flaw to escalate
their privileges on the system. (CVE-2016-4565, Important)
* A race condition flaw was found in the way the Linux kernel's SCTP
implementation handled sctp_accept() during the processing of heartbeat
timeout events. A remote attacker could use this flaw to prevent further
connections to be accepted by the SCTP server running on the system,
resulting in a denial of service. (CVE-2015-8767, Moderate)
* A flaw was found in the way the realtime kernel processed specially
crafted ICMP echo requests. A remote attacker could use this flaw to
trigger a sysrql function based on values in the ICMP packet, allowing them
to remotely restart the system. Note that this feature is not enabled by
default and requires elevated privileges to be configured. (CVE-2016-3707,
Moderate)
Red Hat would like to thank Jann Horn for reporting CVE-2016-4565.
Bug Fix(es):
* An oops can occur in the hpsa driver while submitting ioaccel2 commands
when the phys_disk pointer is NULL (in hpsa_scsi_ioaccel_raid_map).
Configuration changes during I/O operations could set the phys_disk
pointer to NULL. In this case, send the command down the RAID path for
correct processing, avoiding the oops. (BZ#1334260)
* A faulty code merge left an extra spin_lock operation in the function
fscache_invalidate_write(). The code has been correctly updated to remove
this extra lock operation, which avoids a potential deadlock situation
when looping through cache pages. (BZ#1327730)

Vulnerability from gsd
Modified

Details
The icmp_check_sysrq function in net/ipv4/icmp.c in the kernel.org projects/rt patches for the Linux kernel, as used in the kernel-rt package before 3.10.0-327.22.1 in Red Hat Enterprise Linux for Real Time 7 and other products, allows remote attackers to execute SysRq commands via crafted ICMP Echo Request packets, as demonstrated by a brute-force attack to discover a cookie, or an attack that occurs after reading the local icmp_echo_sysrq file.

Details
The icmp_check_sysrq function in net/ipv4/icmp.c in the kernel.org projects/rt patches for the Linux kernel, as used in the kernel-rt package before 3.10.0-327.22.1 in Red Hat Enterprise Linux for Real Time 7 and other products, allows remote attackers to execute SysRq commands via crafted ICMP Echo Request packets, as demonstrated by a brute-force attack to discover a cookie, or an attack that occurs after reading the local icmp_echo_sysrq file.
