______________________________________________________________________________
An update that solves 14 vulnerabilities and has 45 fixes
is now available.
Description:
The SUSE Linux Enterprise 11 SP3 Realtime kernel was updated to receive
various security and bugfixes.
The following feature was added for RT:
- FATE#317131: The SocketCAN (Peak PCI) driver was added for CAN bus
support.
Following security bugs were fixed:
- CVE-2015-5707: An integer overflow in the SCSI generic driver could be
potentially used by local attackers to crash the kernel or execute code
(bsc#940338).
- CVE-2015-5364: A remote denial of service (hang) via UDP flood with
incorrect package checksums was fixed. (bsc#936831).
- CVE-2015-5366: A remote denial of service (unexpected error returns) via
UDP flood with incorrect package checksums was fixed. (bsc#936831).
- CVE-2015-1420: A race condition in the handle_to_path function in
fs/fhandle.c in the Linux kernel allowed local users to bypass intended
size restrictions and trigger read operations on additional memory
locations by changing the handle_bytes value of a file handle during the
execution of this function (bnc#915517).
- CVE-2015-4700: A local user could have created a bad instruction in the
JIT processed BPF code, leading to a kernel crash (bnc#935705).
- CVE-2015-4167: The UDF filesystem in the Linux kernel was vulnerable to
a crash which could occur while fetching inode information from a
corrupted/malicious udf file system image. (bsc#933907).
- CVE-2014-9728 CVE-2014-9729 CVE-2014-9730 CVE-2014-9731: Various issues
in handling UDF filesystems in the Linux kernel allowed the corruption
of kernel memory and other issues. An attacker able to mount a
corrupted/malicious UDF file system image could cause the kernel to
crash. (bsc#933904 bsc#933896)
- CVE-2015-2150: The Linux kernel did not properly restrict access to PCI
command registers, which might have allowed local guest users to cause a
denial of service (non-maskable interrupt and host crash) by disabling
the (1) memory or (2) I/O decoding for a PCI Express device and then
accessing the device, which triggers an Unsupported Request (UR)
response (bsc#919463).
- CVE-2015-0777: drivers/xen/usbback/usbback.c as used in the Linux kernel
2.6.x and 3.x in SUSE Linux distributions, allowed guest OS users to
obtain sensitive information from uninitialized locations in host OS
kernel memory via unspecified vectors (bnc#917830).
- CVE-2015-2830: arch/x86/kernel/entry_64.S in the Linux kernel did not
prevent the TS_COMPAT flag from reaching a user-mode task, which might
have allowed local users to bypass the seccomp or audit protection
mechanism via a crafted application that uses the (1) fork or (2) close
system call, as demonstrated by an attack against seccomp before 3.16
(bnc#926240).
- CVE-2015-1805: The Linux kernels implementation of vectored pipe read
and write functionality did not take into account the I/O vectors that
were already processed when retrying after a failed atomic access
operation, potentially resulting in memory corruption due to an I/O
vector array overrun. A local, unprivileged user could use this flaw to
crash the system or, potentially, escalate their privileges on the
system. (bsc#933429).

- audit: keep inode pinned (bsc#851068).

(bnc#942350).

- drm/cirrus: do not attempt to acquire a reservation while in an
interrupt handler (bsc#935572).

interrupt handler (bsc#935572).
