SUSE SLED11 / SLES11 Security Update : kernel (SUSE-SU-2015:1611-1)

High Nessus Plugin ID 86121

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The SUSE Linux Enterprise 11 SP3 kernel was updated to receive various security and bugfixes.

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).

The update package also includes non-security fixes. See advisory for details.
