Test Kennung:1.3.6.1.4.1.25623.1.0.68715
Kategorie:Red Hat Local Security Checks
Titel:RedHat Security Advisory RHSA-2011:0004
Zusammenfassung:Redhat Security Advisory RHSA-2011:0004
Beschreibung:The remote host is missing updates announced in
advisory RHSA-2011:0004.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

This update fixes the following security issues:

* A flaw was found in sctp_packet_config() in the Linux kernel's Stream
Control Transmission Protocol (SCTP) implementation. A remote attacker
could use this flaw to cause a denial of service. (CVE-2010-3432,
Important)

* A missing integer overflow check was found in snd_ctl_new() in the Linux
kernel's sound subsystem. A local, unprivileged user on a 32-bit system
could use this flaw to cause a denial of service or escalate their
privileges. (CVE-2010-3442, Important)

* A heap overflow flaw in the Linux kernel's Transparent Inter-Process
Communication protocol (TIPC) implementation could allow a local,
unprivileged user to escalate their privileges. (CVE-2010-3859, Important)

* An integer overflow flaw was found in the Linux kernel's Reliable
Datagram Sockets (RDS) protocol implementation. A local, unprivileged user
could use this flaw to cause a denial of service or escalate their
privileges. (CVE-2010-3865, Important)

* A flaw was found in the Xenbus code for the unified block-device I/O
interface back end. A privileged guest user could use this flaw to cause a
denial of service on the host system running the Xen hypervisor.
(CVE-2010-3699, Moderate)

* Missing sanity checks were found in setup_arg_pages() in the Linux
kernel. When making the size of the argument and environment area on the
stack very large, it could trigger a BUG_ON(), resulting in a local denial
of service. (CVE-2010-3858, Moderate)

* A flaw was found in inet_csk_diag_dump() in the Linux kernel's module for
monitoring the sockets of INET transport protocols. By sending a netlink
message with certain bytecode, a local, unprivileged user could cause a
denial of service. (CVE-2010-3880, Moderate)

* Missing sanity checks were found in gdth_ioctl_alloc() in the gdth driver
in the Linux kernel. A local user with access to /dev/gdth on a 64-bit
system could use this flaw to cause a denial of service or escalate their
privileges. (CVE-2010-4157, Moderate)

* The fix for Red Hat Bugzilla bug 484590 as provided in RHSA-2009:1243
introduced a regression. A local, unprivileged user could use this flaw to
cause a denial of service. (CVE-2010-4161, Moderate)

* A NULL pointer dereference flaw was found in the Bluetooth HCI UART
driver in the Linux kernel. A local, unprivileged user could use this flaw
to cause a denial of service. (CVE-2010-4242, Moderate)

* It was found that a malicious guest running on the Xen hypervisor could
place invalid data in the memory that the guest shared with the blkback and
blktap back-end drivers, resulting in a denial of service on the host
system. (CVE-2010-4247, Moderate)

* A flaw was found in the Linux kernel's CPU time clocks implementation for
the POSIX clock interface. A local, unprivileged user could use this flaw
to cause a denial of service. (CVE-2010-4248, Moderate)

* Missing initialization flaws in the Linux kernel could lead to
information leaks. (CVE-2010-3876, CVE-2010-4083, Low)
