SUSE SLED12 / SLES12 Security Update : kernel (SUSE-SU-2015:1071-1)

High Nessus Plugin ID 84227

Synopsis

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

Description

The SUSE Linux Enterprise 12 kernel was updated to version 3.12.43 to receive various security and bugfixes.

Following security bugs were fixed :

- CVE-2014-3647: arch/x86/kvm/emulate.c in the KVM subsystem in the Linux kernel through 3.17.2 did not properly perform RIP changes, which allowed guest OS users to cause a denial of service (guest OS crash) via a crafted application (bsc#899192).

- CVE-2014-8086: Race condition in the ext4_file_write_iter function in fs/ext4/file.c in the Linux kernel through 3.17 allowed local users to cause a denial of service (file unavailability) via a combination of a write action and an F_SETFL fcntl operation for the O_DIRECT flag (bsc#900881).

- CVE-2014-8159: The InfiniBand (IB) implementation did not properly restrict use of User Verbs for registration of memory regions, which allowed local users to access arbitrary physical memory locations, and consequently cause a denial of service (system crash) or gain privileges, by leveraging permissions on a uverbs device under /dev/infiniband/ (bsc#914742).

- CVE-2015-1465: The IPv4 implementation in the Linux kernel before 3.18.8 did not properly consider the length of the Read-Copy Update (RCU) grace period for redirecting lookups in the absence of caching, which allowed remote attackers to cause a denial of service (memory consumption or system crash) via a flood of packets (bsc#916225).

- CVE-2015-2041: net/llc/sysctl_net_llc.c in the Linux kernel before 3.19 used an incorrect data type in a sysctl table, which allowed local users to obtain potentially sensitive information from kernel memory or possibly have unspecified other impact by accessing a sysctl entry (bsc#919007).

- CVE-2015-2042: net/rds/sysctl.c in the Linux kernel before 3.19 used an incorrect data type in a sysctl table, which allowed local users to obtain potentially sensitive information from kernel memory or possibly have unspecified other impact by accessing a sysctl entry (bsc#919018).

- CVE-2015-2666: Fixed a flaw that allowed crafted microcode to overflow the kernel stack (bsc#922944).

- CVE-2015-2830: Fixed int80 fork from 64-bit tasks mishandling (bsc#926240).

- CVE-2015-2922: Fixed possible denial of service (DoS) attack against IPv6 network stacks due to improper handling of Router Advertisements (bsc#922583).

- CVE-2015-3331: Fixed buffer overruns in RFC4106 implementation using AESNI (bsc#927257).

- CVE-2015-3332: Fixed TCP Fast Open local DoS (bsc#928135).

- CVE-2015-3339: Fixed race condition flaw between the chown() and execve() system calls which could have lead to local privilege escalation (bsc#928130).

- CVE-2015-3636: Fixed use-after-free in ping sockets which could have lead to local privilege escalation (bsc#929525).

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.
