SUSE SLED12 / SLES12 Security Update : kernel (SUSE-SU-2015:0529-1)

high Nessus Plugin ID 83702

Language:

Synopsis

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

Description

The SUSE Linux Enterprise 12 kernel was updated to 3.12.38 to receive various security and bugfixes.

This update contains the following feature enablements :

- The remote block device (rbd) and ceph drivers have been enabled and are now supported. (FATE#318350) These can be used e.g. for accessing the SUSE Enterprise Storage product services.

- Support for Intel Select Bay trail CPUs has been added.
(FATE#316038)

Following security issues were fixed :

- CVE-2014-9419: The __switch_to function in arch/x86/kernel/process_64.c in the Linux kernel through 3.18.1 did not ensure that Thread Local Storage (TLS) descriptors were loaded before proceeding with other steps, which made it easier for local users to bypass the ASLR protection mechanism via a crafted application that reads a TLS base address (bnc#911326).

- CVE-2014-7822: A flaw was found in the way the Linux kernels splice() system call validated its parameters.
On certain file systems, a local, unprivileged user could have used this flaw to write past the maximum file size, and thus crash the system.

- CVE-2014-8160: The connection tracking module could be bypassed if a specific protocol module was not loaded, e.g. allowing SCTP traffic while the firewall should have filtered it.

- CVE-2014-9584: The parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel before 3.18.2 did not validate a length value in the Extensions Reference (ER) System Use Field, which allowed local users to obtain sensitive information from kernel memory via a crafted iso9660 image (bnc#912654).

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

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
