The remote Scientific Linux host is missing one or more security
The kernel packages contain the Linux kernel, the core of any Linux
This update fixes the following security issues :
- Multiple buffer overflow flaws were found in the Linux
kernel's Management Module Support for Message Passing
Technology (MPT) based controllers. A local,
unprivileged user could use these flaws to cause a
denial of service, an information leak, or escalate
their privileges. (CVE-2011-1494, CVE-2011-1495,
- A flaw was found in the Linux kernel's Ethernet bonding
driver implementation. Packets coming in from network
devices that have more than 16 receive queues to a
bonding interface could cause a denial of service.
- A flaw was found in the Linux kernel's networking
subsystem. If the number of packets received exceeded
the receiver's buffer limit, they were queued in a
backlog, consuming memory, instead of being discarded. A
remote attacker could abuse this flaw to cause a denial
of service (out-of-memory condition). (CVE-2010-4251,
- A flaw was found in the Linux kernel's Transparent Huge
Pages (THP) implementation. A local, unprivileged user
could abuse this flaw to allow the user stack (when it
is using huge pages) to grow and cause a denial of
service. (CVE-2011-0999, Moderate)
- A flaw was found in the transmit methods (xmit) for the
loopback and InfiniBand transports in the Linux kernel's
Reliable Datagram Sockets (RDS) implementation. A local,
unprivileged user could use this flaw to cause a denial
of service. (CVE-2011-1023, Moderate)
- A flaw in the Linux kernel's Event Poll (epoll)
implementation could allow a local, unprivileged user to
cause a denial of service. (CVE-2011-1082, Moderate)
- An inconsistency was found in the interaction between
the Linux kernel's method for allocating NFSv4 (Network
File System version 4) ACL data and the method by which
it was freed. This inconsistency led to a kernel panic
which could be triggered by a local, unprivileged user
with files owned by said user on an NFSv4 share.
- A missing validation check was found in the Linux
kernel's mac_partition() implementation, used for
supporting file systems created on Mac OS operating
systems. A local attacker could use this flaw to cause a
denial of service by mounting a disk that contains
specially crafted partitions. (CVE-2011-1010, Low)
- A buffer overflow flaw in the DEC Alpha OSF partition
implementation in the Linux kernel could allow a local
attacker to cause an information leak by mounting a disk
that contains specially crafted partition tables.
- Missing validations of null-terminated string data
structure elements in the do_replace(),
do_ip6t_get_ctl(), and do_arpt_get_ctl() functions could
allow a local user who has the CAP_NET_ADMIN capability
to cause an information leak. (CVE-2011-1170,
CVE-2011-1171, CVE-2011-1172, Low)
This update also fixes several hundred bugs and adds enhancements.
The system must be rebooted for this update to take effect.
